Via Francigena (Schweiz)

At a Glance

• Start / Finish: Ballaigues (861 m, border at Jougne) → Col du Grand-Saint-Bernard (2,469 m) — the highest point on the entire Via Francigena from Canterbury to Rome
• Length: 195.0 km
• Ascent/Descent: ↗ 8,200 m / ↘ 6,614 m — 42 meters of elevation gain per kilometer: The trail first descends toward Lake Geneva (lowest point: Vevey, 383 m) and then climbs over 2,000 meters to the pass
• Duration: 10 stages, 10–12 days — the first seven stages stay below 500 meters in elevation, while the last three take you up about 2,000 meters
• Best time: Late June through mid-September — the mountain pass is open only from June through September; in winter, there can be up to ten meters of snow up there
• Marking: Via Francigena, SchweizMobil Route 70 (regional hiking trail, continuously marked), plus the Via Francigena logo
• Pilgrim documents: Credential from the Association Suisse de la Via Francigena, CHF 8.00; the Testimonium is only available in Rome—not on the pass—and it is not a Compostela
• Connection: In Ballaigues, the Via Francigena (France) ends, and at the pass, the Via Francigena (Italy) begins; in Lausanne, the Via Jacobi crosses it on its way to Santiago
• Character: The Rome Route, not the Camino de Santiago—ten stages whose place names have been recorded in an English manuscript since 990; no network of inns, but a hospice at 2,469 meters that has been in operation since around 1050

Overview

The Via Francigena (Schweiz) is the Alpine section of the Great Rome Line from Canterbury: 195.0 Kilometers by Ballaigues along the French border via Orbe, Lausanne, and the vineyard terraces of the Lavaux and up the Rhône Valley to the Col du Grand-Saint-Bernard — at 2,469 meters, the highest point on the entire route to Rome. In between are 8,200 meters of elevation gain The elevation gain is 42 per kilometer, and the distribution is, as expected, unfair: For seven stages, the route feels like a hike around Lake Geneva, then the last three lift you up by about 2,000 meters. And it has something that hardly any other trail in our collection has: its sequence of towns has been recorded in black and white in an English manuscript for over a thousand years. Archbishop Sigerich of Canterbury On the way home from Rome, 990 listed 80 stopover locations—seven of which are in Switzerland, in the exact order in which you’ll visit them. You're not following a reconstructed route. You're working through a list.

The finale has the longest history along this route: At the top of the pass stood a temple to Jupiter, in which the Celtic god Poeninus was worshipped around 50 small bronze plaques were sacrificed; for about 1050 The Bernhard von Aosta hospice stands there, and the Augustinian canons have been running it to this day—until 1940, a night’s stay was free. The Codex Calixtinus, the pilgrim’s guide to Santiago, listed it around 1135 as one of the three “pillars of the world,” alongside Jerusalem and Santa Cristina at Somport. And so, to be honest about what this route deserves: This is Not the Camino de Santiago. The apostle at the end of the line is Peter; the document at the destination is the *Testimonium*, not *Compostela* — in 2025, there were well over 12.000 Of those, 530,987 Compostelas were issued in Santiago that same year. That’s a ratio of 44 to 1, and it’s not a warning but an offer: You won’t have to wait in line here.

Seven Names in an English Manuscript

990 traveled Sigerich, Archbishop of Canterbury, traveled to Rome to receive the pallium from Pope John XV. Only the return journey has been recorded: 80 stops along the way, a good 1,700 kilometers, documented in a manuscript at the British Library (Cotton Tiberius B.v), titled Iste sunt submansiones de Roma usque ad mare. — These are the stops along the route from Rome to the sea. Seven of these submansiones are located in Switzerland, and they are listed in the order in which you will pass through them: XLIX Petrescastel (Bourg-Saint-Pierre), L Ursiores (Orsières), LI sancte Maurici (Saint-Maurice), LII Burbulei (Versvey), LIII Uiuaec (Vevey), LIIII Losanna (Lausanne), LV Urba (Orbe). At LVI Antifern — now called Jougne — the route crosses into France: this is the exact border where the Via Francigena (France) hands off the path to this section, and your first day begins. This handoff isn’t just a bureaucratic formality; it’s been documented—since 990. And the names tell a story: Urba It sounds like "urbs," meaning "city"—but it comes from the Celtic word "orobis" and simply means "river." The archbishop did not record a city, but a river. And around 972, Ursiores was still called Pons Ursarii, the Bear Bridge.

The list is not an obituary for something that has disappeared—it was compiled while its author was still alive. In Romainmôtier, the most rewarding stop on the second leg, is home to an abbey church modeled after the Cluniac tradition, built between 990 and 1028 — so it began in the year that Sigerich crossed Switzerland. And in Bourg-Saint-Pierre, his Petrescastel, the people built 1011 through 1019 the church tower, which the community now calls the oldest in Valais. The path was not reconstructed—it was built over while the archbishop was still on his way. The oldest house along the path is actually five centuries older: At the September 22, 515 King Sigismund of Burgundy founded the abbey Saint-Maurice at the graves of the Theban legionnaires—the oldest continuously existing monastery in the Western world. The legend behind it is recounted by Bishop Eucherius of Lyon around 430–440: 6,600 soldiers refused to obey the emperor’s order, and their response was a declaration of loyalty that drew a clear line in a single sentence:“As soldiers, we belong to you, Emperor, but we are also, as we freely admit, servants of God.” Modern ancient historians dispute that this legion ever existed—and that is precisely the point: Whether those 6,600 men actually existed remains an open question. The fact that prayers have been offered at this site without interruption since 515 is not a legend, but institutional history. Even in the case of the famous laus perennis As for the choral singing that rotates day and night, let’s be precise: It began in 522/523 and ended in its original form in the 9th century—the house’s tradition of prayer has continued uninterrupted ever since, though not the 24-hour chant. The honest version is the more compelling one anyway.

And the destination is older than any name on the list. At 2,469 meters—the highest point on the entire Via Francigena—stood a temple measuring 7.4 by 11.3 meters dedicated to the Celtic god Poeninus, whom the Romans identified with Jupiter — about 50 small bronze plaques were offered to him, along with Celtic coins; the artifacts are now on display at the Hospizmuseum, and the sanctuary was 394 was destroyed, and from then on the pass was called Mons Iovis, Jupiter Mountain—in French, Mont-Joux. Around 1049/1050 Bernhard von Aosta founded a hospice on that very spot, whose guiding principle has been handed down: “Its doors were open to anyone who crossed the pass, regardless of social status.” It is still in operation today. The Codex Calixtinus Around 1135, it was counted among the three hospices that the Lord had “established as pillars in this world,” “which are absolutely necessary for the support of His poor”—alongside Jerusalem and Santa Cristina at Somport (Book V, Chapter IV). The guidebook to Santiago recommends the house where you'll be staying on your way to Rome. And at the other end, near Ballaigues, the remains of Roman roads and a cart track carved into the rock for transporting salt can be found in the forest. On the first day, you'll walk along wagon tracks; on the last day, you'll stand at a sacrificial site.

Other Names

Via Francigena Literally means “the road that comes from the Franks”: From an Italian perspective, this road came from the Frankish Kingdom, and that is how it got its name. The name of our page Via Francigena (Schweiz) refers to the Swiss section of the major Canterbury–Rome route; older German texts also say Frankenweg or simply the Rome Route—which has nothing to do with the Franconian Way of St. James—in French, you'll read Chemin des Francs. In the Swiss hiking trail network, this section is called ViaFrancigena, Route 70 On SchweizMobil: a regional route (two-digit number—national routes have single-digit numbers), but consistently signposted, and that is precisely the key practical advantage of this route. The Council of Europe designated the Via Francigena a Cultural Route in 1994 and a Grand Itinéraire Culturel in 2004; the current entire system spans 3,268 kilometers from Canterbury to Santa Maria di Leuca, coordinated by the AEVF—of which the Swiss sponsoring association is also a member, the Association Suisse de la Via Francigena.

Who It's Ideal For—and Who It's Not So Ideal For

This trail is for you if you’re looking for a short, very intense long-distance hike with a real grand finale: ten stages, each with its own theme—the Jura escarpment, a Roman villa, cathedral, UNESCO vineyards, Rhône Valley, the oldest monastery in the Western world, a Roman town, an Alpine valley, and a mountain pass. It’s also ideal if you the entire Via Francigena you go, and Switzerland lies in between as part of the Alps—or if you study history occupied If you want proof rather than just a claim: Hardly any route can be traced back to a primary source as precisely as this one can to Sigerich’s list from 990. And it’s ideal if you like peace and quiet: In 2025, a good 12,000 Testimonium were issued along the entire Via Francigena, compared to 530,987 Compostelas in Santiago that same year. Over the course of ten stages, you’ll probably meet more winemakers than pilgrims.

To be honest, though, it's not for you if you're on a tight budget — Switzerland is expensive, and there isn't a hostel network like the one in Spain: You'll stay in hotels, B&Bs, and hostels, and occasionally in church-run lodging. It’s also not for you outside of summer: The mountain pass is only open from June through September; in winter, there’s up to ten meters of snow up there, and the final leg is alpine terrain, not a lakeside path. And it’s not for you if you’re looking for the Way of St. James—this one leads to Rome, the destination is St. Peter’s, and at the end there’s no Compostela, just the Testimonium. If you want the scallop shell, turn onto the Via Jacobi from; see below for where this is possible.

Route & Landscape

The trail starts downhill. From Ballaigues at 861 meters — three kilometers from Vallorbe, right on the border near Jougne — he falls through the Orbe Gorge with its waterfalls flowing down to World to 479 meters, past the salt cart track carved into the rock and the largest Roman estate complex in Switzerland, whose mosaics at Boscéaz are right there. Then the Vaud hills across Cossonay and down the Jorat Ridge to Lake Geneva, to Lausanne — From the cathedral terrace, you’ll see for the first time where the journey is headed. And there, two long-distance routes intersect: the Via Jacobi turns west toward Geneva and Santiago, while your Route 70 heads east along the lake shore toward Rome. When you’re in Lausanne, you’re not deciding on the next leg of the journey, but on which apostle to follow.

From Lausanne on, the scenery becomes spectacular; from Vevey on, it’s a steady climb. Only then does the Lavaux: Over 805 hectares of terraced vineyards overlooking the lake, a UNESCO World Heritage Site since 2007, cultivated since the 12th century—here you’ll gain elevation without even noticing it, because the path winds constantly up and down through the vineyard walls. At Vevey (383 m) marks the lowest point. Then the Rhône Valley and Chablais until Aigle, the gorge of Saint-Maurice with the abbey dating from 515, the sharp bend in the Rhône Valley near the Roman Martigny — and then the trail leaves the valley for good and climbs into the Val d'Entremont: Orsières, Bourg-Saint-Pierre at 1,632 meters and most recently, due to the Combe des Morts, the Col du Grand-Saint-Bernard at 2,469 meters. The elevation gain from Vevey to the pass is over 2,000 meters. Incidentally, the name of the last valley—the Valley of the Dead—is not just a marketing ploy.

Stages, Terrain & Difficulty

For once, you don't have to cut anything yourself: The trail operator divides the Swiss section into ten stages, and Route 70 is marked exactly that way — Anyone who plans differently will struggle with the trail markers and the lack of lodging. 195.0 kilometers averages out to 19.5 per day, but the average is misleading: The first seven stages stay below 500 meters in elevation, while the last three take you up about 2,000 meters, and the final stage, at about 12 kilometers, is the shortest and at the same time the toughest—837 meters of elevation gain in one go, alpine terrain, only in snow-free conditions. About half the route is on natural trails, with asphalt in between, especially in the Rhône Valley. Fitness enthusiasts combine Stages 1 and 2 (Ballaigues → Cossonay, about 36 km, mostly downhill)—the often-recommended alternative of Aigle → Martigny in one day means you’ll miss the Abbey of Saint-Maurice, and that’s a bad trade-off.

1. Ballaigues → Orbe — approx. 16 km — descending from 861 to 479 m through the Orbe Gorge with waterfalls and rapids. At the beginning, the one carved into the rock Salt-Covered Cart Tracks, just before Orbe, the Mosaics from Boscéaz.
2. Orbe → Cossonay — approx. 20 km — the Vaud hills: via Croy to the Romainmôtier Abbey Church (built 990–1028), then via La Sarraz to Cossonay—the most worthwhile stop along the route is right here on the way.
3. Cossonay → Lausanne — approx. 22 km — down the Jorat Ridge to Lake Geneva. Destination: Notre-Dame Cathedral, consecrated in 1275. This is where the Via Jacobi.
4. Lausanne → Vevey — approx. 24 km — the showcase stage: Lavaux, a UNESCO World Heritage Site since 2007, with over 805 hectares of terraces overlooking the lake and a constant series of ups and downs along the vineyard walls. Lowest point of the trail: Vevey, 383 m.
5. Vevey → Aigle — about 22 km — around the end of the lake, then through the Rhône Valley and Chablais. Goal: Aigle Castle (early 13th century, burned down in 1475), now a wine museum.
6. Aigle → Saint-Maurice — approx. 19 km — flat through the Rhone Valley to the valley gorge. Destination: the Saint-Maurice Abbey, in continuous operation since 515 — basilica, catacombs, treasury. The most intense half-day of the trip.
7. Saint-Maurice → Martigny — approx. 17 km — the Rhône Valley to the sharp bend in the valley. Destination: the Roman Forum Claudii Vallensium — Amphitheater, Mithraeum, and Barryland, the St. Bernard Museum.
8. Martigny → Orsières — approx. 22 km — the trail leaves the Rhône Valley and climbs into the Val d'Entremont, from about 471 to about 900 m. Alternative route: the historic high-altitude route via Chemin-Dessus.
9. Orsières → Bourg-Saint-Pierre — approx. 21 km — Mountain villages in the Entremont region, climbing steadily to 1,632 m. Destination: Sigerichs Petrescastel with the the oldest church tower in Valais (1011–1019) and the Constantine Milestone. Book a bed in advance.
10. Bourg-Saint-Pierre → Col du Grand-Saint-Bernard — approx. 12 km — Queen Stage: 837 meters of elevation gain to 2,469 meters, the last stretch through the Combe des Morts. Above: Hospice, Canons, St. Bernardines — and Italy.

As the official version, the operator offers the Stage 1bis from Sainte-Croix to Orbe (train service via Yverdon-les-Bains); Romainmôtier On Stage 2, however, there is no detour—the route runs right past the abbey church. On Stage 8, there is also the old high-altitude route via Chemin-Dessus. And the most important planning tip comes at the end: Outside the months of June through September, the final leg is not a hiking trail—during that time, you walk to Bourg-Saint-Pierre and take the bus through the tunnel (5.85 km, opened in 1964; walking through it is prohibited). That’s not a shame—it’s the rule.

Highlights Along the Way

• Salt Cart Track near Ballaigues — wagon tracks carved into the rock from historic salt transport, right on the first day; in the forest nearby lie preserved remains of a Roman road.
• Mosaics from Orbe-Boscéaz — nine mosaics in their original locations in a villa rustica dating from around 170 A.D., spread over 16 hectares—the finest collection of Roman mosaics north of the Alps. The centerpiece (ca. 200–230 AD) depicts the seven gods of the week: seven days, seven gods—and you walk past them in ten stages on your way to an apostle’s tomb.
• Romainmôtier Abbey Church (Stage 2) — Built between 990 and 1028, one of the oldest Romanesque structures in Switzerland; construction began in the year of Sigerich’s visit; today, it is the intersection of three Council of Europe Cultural Routes.
• Notre-Dame de Lausanne Cathedral — consecrated in 1275 in the presence of Pope Gregory X and King Rudolf of Habsburg; the painted portal (c. 1225–1235) still retains its original paintwork. And since 1405, the Guet every hour at night from the tower—to this day, at the fork in the road between Rome and Santiago.
• Lavaux — Over 805 hectares of vineyard terraces overlooking Lake Geneva, a UNESCO World Heritage Site since June 28, 2007; the terraces date back to the 12th century; the grape variety is Chasselas.
• Aigle Castle — Early 13th century; burned down by the Bernese in 1475 and rebuilt; served as a district prison until 1972; today a museum of viticulture and wine. And the town’s name is an 850-year-old trap: Aigle It does not come from the eagle, but from the personal name Agil—yet the coat of arms still features two eagles, a "speaking" coat of arms based on a misinterpretation. The city itself is the result of this translation error.
• Saint-Maurice Abbey — founded on September 22, 515, by King Sigismund, the oldest continuously existing monastery in the Western world; A basilica, catacombs, an archaeological site, and one of Europe’s richest church treasures, including vessels from the 1st century B.C. and a golden jug, a gift from Charlemagne.
• Martigny — the Roman Forum of Claudii Vallensium, with its amphitheater and mithraeum; its predecessor, Octodurus, is already mentioned by Caesar. In addition, Barryland, which is now the St. Bernard breeding station.
• Bourg-Saint-Pierre — Sigerichs Petrescastel: The oldest church tower in Valais (1011–1019); at the foot of the church stands a Roman milestone dedicated to Emperor Constantine, which indicates that Martigny is 24 Roman miles away. And an unresolved matter: On May 20, 1800, Napoleon crossed the pass with some 40,000 men; among other things, the village supplied 22,000 bottles of wine — Napoleon did not pay, but left behind a promissory note for 40,000 francs. In 1805, France paid 18,000; the municipality demanded the remainder, plus interest, from Mitterrand in 1983. In May 1984, instead of money, a commemorative medal nearly one meter in diameter was delivered—and with that, the case was considered closed after 184 years. The promissory note, medal, and letter remain in the village to this day.
• Hospice on the Great St. Bernard Pass — 2,469 m, the highest point on the entire Via Francigena; founded around 1049/1050, attested as a house of Augustinian canons since 1125, and listed in the Codex Calixtinus as one of the three “pillars of the world” alongside Jerusalem and Santa Cristina on the Somport Pass. This is where the St. Bernard breed originated in the 17th century—the most famous dog, Barry, is said to have saved over forty people. You can still stay the night there today, and it’s the best way to spend your last evening on this trail.

How Pilgrims Find Their Way onto This Path

The most natural way to arrive is on foot: The Via Francigena (Frankreich) comes from the English Channel, passing through Champagne and the French Jura to Jougne — and there, at the border above Vallorbe, the Swiss section begins at Ballaigues. This is not an administrative boundary, but a documented one: In Sigerich’s list from 990, Jougne is submansio LVI (Antifern) and Orbe, the LV (Urba) — For over a thousand years, the path has been changing the landscape here, and our two sides pass it on to each other at the same point, just like the manuscript.

If you don't walk the entire route, you can hop on the train—and that's what this path is built for: Vallorbe is a border station with a TGV stop (Lyria Lausanne–Paris); from there, it is three kilometers to Ballaigues; Orbe, Cossonay, Lausanne, Vevey, Aigle, Saint-Maurice, and Martigny They're all along the railroad tracks; the trail follows the Simplon Line for long stretches. And in Lausanne There you'll find the most interesting turnout in Switzerland: That's where the Via Jacobi, National Route 4 from Rorschach to the French border. Standing on the cathedral terrace, you don’t decide on the next leg of the journey, but on which apostle to follow—eastward to Rome, westward to Santiago. Your Credenziale You can order it in advance from the Swiss association; it costs CHF 8.00.

Continue the pilgrimage?

This trail does not end at the top of the pass—it continues on. Behind the hospice, the Via Francigena (Italien): About Saint-Rhémy — Sigerich's Sancte remei, submansio XLVIII — down into the Aosta Valley and on through the Po Valley and Tuscany to St. Peter’s Basilica, about 1,000 kilometers to go, and by then you’ll already have passed the highest point of the entire route. If you trace the route from the other end, you’ll find the Via Francigena (Frankreich) all the way up to the English Channel. At the end, in Rome, there is the Testimonium — It's only there; not on the pass.

And if your ultimate destination is Santiago after all, the transfer is already built into the route: In Lausanne intersects the Via Jacobi, 446 kilometers from Rorschach to the French border. From Geneva, the route continues as Via Gebennensis next, then as Via Podiensis via Le Puy-en-Velay to Saint-Jean-Pied-de-Port, where the Camino Francés begins. Two apostles, a cathedral terrace—the decision is made in Lausanne, not at the destination.

Preparation & Practical Information

The time frame is tight, and there's no getting around that. The mountain pass road to the Great St. Bernard is open only from June through September; in winter, there is up to ten meters of snow at the top, and the annual average temperature at the pass is 4.3 degrees. Realistically, Late June through mid-September — and even then, a summer snowfall can make the Combe des Morts impassable. If you're traveling outside of this period, walk to Bourg-Saint-Pierre and take the bus through the tunnel; walking through the tunnel is prohibited.

Pack as if you're going to the mountains, not to the lake. The first seven stages are valley hikes with some paved sections; the last three are alpine terrain with about 2,000 meters of elevation gain: ankle-high boots with tread, rain and wind protection, a warm layer for the pass summit—where temperatures drop to single digits at night in August—and enough water for Stage 10. If you’re in the Hospice If you're staying in the dormitory, a sleeping bag is required (not in the rooms); in both cases, you'll need to bring your own towels. And making a reservation for Stages 9 and 10 isn’t just a nice-to-have: Bourg-Saint-Pierre is a village at 1,632 meters with few beds, and the hostel is regularly full in the summer—you plan for these gaps in advance, not on the go.

Papers and stamps. You need a Credenziale; the one from the Swiss association costs CHF 8.00. You can get stamps at parish offices, tourist offices, and the Saint-Maurice Abbey — which runs its own pilgrim reception program — and at the hospice. At the end of the entire route, in Rome, is the Testimonium, not the Compostela, and expect to have to explain yourself along the way: With 12,000 Testimoniums compared to 530,987 Compostelas in 2025, not every innkeeper between Orbe and Orsières will immediately know what you want. Plan your daily stages in advance, because accommodations are unevenly distributed and fill up quickly in the summer—the easiest way to do this is directly in the Camino Ninja app, where you can put together your stages and plan suitable accommodations at the same time.

What the journey will cost you

Switzerland is expensive, and this route is no exception: There isn’t a hostel network like the one in Spain; you’ll mostly stay in hotels, B&Bs, inns, and youth hostels, and occasionally in church-run lodgings. Expect to pay CHF 80–150 per day (As of August 2026), based on a double room with breakfast included—those traveling alone will be at the higher end of the range. Sample prices: youth hostel CHF 40–70, simple hotel or B&B in a double room CHF 100–170, daily special CHF 20–30, coffee CHF 4–5; around the time of the Montreux Jazz Festival in July, prices on the Riviera between Lausanne and Vevey rise sharply—book early there. You can save money in three ways: cooking your own meals with groceries from Coop and Migros (the route passes through cities, so you’ll see stores everywhere), staying at church-run or simple pilgrim lodgings—which are significantly cheaper than hotels—and spending the night at the Hospice on the Great St. Bernard Pass, half-board—it’s best to call directly to find out the current price (+41 27 787 12 36); by the way, meals there were free until 1940. The Credenziale costs CHF 8.00, and if you’re planning multiple train trips—the trip there, stops along the way, and the return trip—consider the Half-Fare Card or the Swiss Travel Pass (all prices are approximate, as of August 2026).

Getting Here

To begin with: Ballaigues is located three kilometers northeast of Vallorbe, and Vallorbe is a real train station—a border station between the Swiss line from Lausanne and the French line to Dijon, served since 1984 by the Lausanne–Paris TGV (now Lyria). So you take the train to Lausanne or Geneva, continue on to Vallorbe, and from there take the PostBus to Ballaigues. If you're traveling through France, you can also stop in Jougne Or get off at Pontarlier and walk the last kilometer in France to the border—then your route begins exactly at Sigerich’s submansio LVI.

From the finish line: At the top of the pass, you'll find yourself at 2,469 meters on the Italian border, with two options. During the summer season, the bus heading north goes down to Orsières, and from there by train via Sembrancher to Martigny (in operation since 1910) and continues along the Simplon Line. To the south, the international bus route connects Martigny–Aosta across the pass; anyone who is in Aosta When you get off, you'll be right on the Via Francigena (Italy) and have access to train service toward Turin and Milan. Important: The Pass buses operate seasonally — Check the schedule before the final leg, not after.

• Getting to the starting point: Take the train to Lausanne or Geneva, then continue to Vallorbe (the TGV Lyria from Paris stops there), then take the PostBus to Ballaigues (3 km); alternatively, take Stage 1bis from Sainte-Croix (train via Yverdon-les-Bains).
• Interim entry: Orbe, Cossonay, Lausanne, Vevey, Aigle, Saint-Maurice, and Martigny are all located along the railroad (Simplon Line); you can reach Orsières by train from Martigny via Sembrancher—the trip can easily be broken up into weekend segments.
• Return trip from the pass: Northbound: Bus to Orsières, train to Martigny (summer season only) — Southbound: Martigny–Aosta bus line, then train from Aosta to Turin/Milan. If the pass is closed: walk to Bourg-Saint-Pierre, then take the bus through the tunnel (closed to pedestrians).
