Overview

Grenoble isn't on a Way of St. James. The region's great pilgrim routes pass by to the north and west. This feeder route brings you to them. It starts at the Cathedral of Notre-Dame, where you get your first stamp at the Maison diocésaine on Place Lavalette, and leaves town through the Porte de France, the city gate the Duke of Lesdiguières had built in 1620.

Then you follow the Isère for a full day, flat and without a single scallop shell along the way. Only at Tullins does the path start to climb, over the Chambaran hills, a forested plateau called "Sylva de Cambaran" in a charter from 1062. On the third day, in the Bièvre plain near Gillonnay, you reach a stele where the ways to Le Puy and to Arles part. According to the ARA, it is 1,751 kilometers from Grenoble to Santiago. You walk the first 25 of them without waymarks, and the last six of this feeder route against them.

Other Names

Via Gebennensis (Grenoble) is a working name used by Camino Ninja. In our system, feeder routes are named after the main route they lead to, with their starting point in parentheses. So this route isn't part of the Via Gebennensis itself, which runs from Geneva to Le Puy. It takes you there.

The Association Rhône-Alpes des Amis de Saint-Jacques (ARA) calls the route the "bretelle de Grenoble", a link path that brings pilgrims from the Grenoble area to the GR 65 at Gillonnay.

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

This route is ideal for you if you live, study or arrive in Grenoble and want to set off for Santiago on foot instead of first taking the train to Geneva or Le Puy. It also works as a three-day start, with a choice at the end between Le Puy and the Mediterranean.

Honestly, though, it's not for you if you want that Camino feeling from day one. The first 25 kilometers are a bike path on the Isère levee, with cyclists, a highway within earshot and no St. James waymarks. It's not for you either if you expect pilgrim hostels: there are hotels and a handful of private hosts you need to call ahead.

Route & Landscape

From Grenoble to Tullins (km 0–28.6): From the cathedral you head to the Isère quay, past the Porte de France (km 1.5) and below the Bastille to Saint-Martin-le-Vinoux (km 2.3). Then the bike path on the Isère levee takes over. On either side rise the limestone walls of the Chartreuse and the Vercors. You continue downstream via Veurey-Voroize (km 13.7); level with the bridge at Saint-Quentin-sur-Isère, the waymarking begins. Through the medieval Porte de Saint-Quentin you enter Tullins (km 28.6).

From Tullins to Gillonnay (km 28.6–57.9): Past Tullins the path climbs more than 500 meters in five kilometers onto the Chambaran hills, through chestnut and beech forest, reaching its highest point at km 34.1. Via La Forteresse (km 36.7), where goat and sheep cheese is made, it rolls up and down to Saint-Michel-de-Saint-Geoirs (km 43.9), then drops to Cours (km 46.6) in the Bièvre plain. In Brézins (km 52.0) you meet the Via Adresca and walk it in reverse for the last six kilometers or so to the stele near Gillonnay.

Stages, Terrain, and Difficulty

The three stages are a Camino Ninja suggestion, set at places with accommodation. Distances come from the Camino Ninja map, calibrated to exactly 57.9 km. Fast walkers split the route at Tullins (km 28.6) and Brézins (km 52.0).

1. Grenoble → Veurey-Voroize (13.7 km) — a half day to warm up, out of the city and downstream on the Isère levee.
2. Veurey-Voroize → La Forteresse (23.0 km) — along the Isère to Tullins, then the only real climb, up onto the Chambaran hills.
3. La Forteresse → Gillonnay (21.2 km) — via Saint-Michel and Cours into the Bièvre, from Brézins on the Via Adresca to the Le Rondet stele; the beds are 3.9 km farther on in La Côte-Saint-André.

Nothing here is technically difficult. The climb past Tullins is steep, and the forest tracks get muddy when wet.

Six Kilometers Against the Arrows

Most feeder routes end where they hit their main route. Not this one. In Brézins, at km 52.0, it crosses the Via Adresca, which runs from Gillonnay via Saint-Antoine-l'Abbaye to Le Puy, and instead of turning onto it, you walk it a good six kilometers back north to its very start. The ARA explicitly warns in its route description that on this stretch the feeder's arrows run against the other route's waymarks. If arrows come toward you pointing the wrong way, you're on the right track.

The reason is the destination: the Le Rondet stele near Gillonnay. It marks the fork "vers Arles et vers Le Puy," where the Via Gebennensis carries on west and the Via Adresca branches off south. If you already know you're heading via Saint-Antoine, turn south straight away in Brézins. And the start of the route is just as quirky: between Grenoble and the bridge at Saint-Quentin-sur-Isère there's no shell and no arrow. A pilgrim route that gets its first waymarks after 25 kilometers and ends up walking against them is, honestly, the best proof that on a Way of St. James it's not the arrows that count, but the direction.

Highlights Along the Way

• Cathédrale Notre-Dame and Musée de l'Ancien Évêché, Grenoble (km 0) — During tramway works in 1989 and 1990, a baptistery from the late 4th century was found beneath the square; it's now in the museum's crypt. In 1084 Bishop Hugh welcomed St. Bruno here, who went on to found the Grande Chartreuse.
• Collégiale Saint-André, Grenoble — founded in 1228 by Dauphin André as the burial church of his dynasty, with the tomb of the knight Bayard.
• Bastille, Grenoble — the fortress above the city, begun in 1591 and expanded from 1824 to 1847. A cable car has run up since 1934, with the spherical cabins, the "bulles," since 1976.
• Tullins (km 28.6) — the Porte de Saint-Quentin from the 13th and 14th centuries, the church of Saint-Laurent-des-Prés, begun in the 11th century, and the Dauphin fountain.
• Notre-Dame-des-Vents near Saint-Michel-de-Saint-Geoirs — a statue of the Virgin from 1954 on the site of a vanished castle, looking out over the Bièvre plain; lightning once decapitated her, and she was restored in 2020.
• Chapelle du Mathais near Cours (km 46.6) — consecrated to Our Lady of Lourdes in 1881; inside is a statue of St. Roch with all the pilgrim attributes, scallop shell, staff and gourd, plus his dog.
• La Côte-Saint-André (3.9 km past the finish) — birthplace of Hector Berlioz in 1803; his childhood home has been a museum since 1935, and a Berlioz festival has been held every summer since 1994. Add to that market halls from the late 13th century.

How Pilgrims Find Their Way onto This Path

Grenoble is a starting point, not a crossing: no other route in Camino Ninja leads here. Three more feeder routes in Camino Ninja lead to the Via Gebennensis:

• Via Gebennensis (Sallanches) — from Mont Blanc down the Arve and along the Salève to Verrières near Geneva
• Via Gebennensis (Saint-Gingolph) — from the Valais along the south shore of Lake Geneva to Geneva
• Via Gebennensis (Col du Petit-Saint-Bernard) — from the Alpine pass on the Italian border through Savoy to Yenne

Continue the pilgrimage?

At the Le Rondet stele you're standing on the Via Gebennensis, at its km 168.8, and at the starting point of the Via Adresca. You have two routes to Le Puy and one to the Mediterranean:

• Via Gebennensis heading west: via La Côte-Saint-André and the Pilat massif, about 178 kilometers more to Le Puy-en-Velay
• Via Adresca heading south: via Saint-Antoine-l'Abbaye, mother house of the Antonine order, and the Vivarais to Le Puy-en-Velay, 222.2 kilometers
• Via Adresca to La Roche-de-Glun on the Rhône, then on along the Via Rhodana to Arles

From Le Puy the Via Podiensis leads to Saint-Jean-Pied-de-Port, where the Camino Francés continues over the Pyrenees to Santiago.

Preparation & Practical Information

Season. The most pleasant months are April to June and September to October. In high summer there's hardly any shade on the levee.

Waymarking and route description. As far as Saint-Quentin-sur-Isère you follow the Isère bike path, then the yellow arrow on a blue background, between Brézins and Gillonnay against the arrows of the Via Adresca, and from the stele the red-and-white of the GR 65. The ARA offers a route description with maps and accommodation as a PDF, available via chemins.compostelleenrhonealpes.fr. You get your first stamp at the Maison diocésaine on Place Lavalette.

Accommodation and credential. You can stay in hotels in Veurey-Voroize and Tullins, in guest rooms in Tullins and with accueils jacquaires, private pilgrim hosts who work on a donation basis, in La Forteresse and Brézins. At the finish, La Côte-Saint-André has plenty of beds, including a gîte run by the Fondation d'Auteuil with pick-up. The easiest way is directly in the Camino Ninja App, where you put your stages together and plan suitable accommodation right along with them. As on all French routes, you need a pilgrim passport (credencial) to stay in pilgrim accommodation and to receive the Compostela at the end. It's best to order it online in advance so it reaches you in time for the start of your trip.

Supplies. You can shop in Grenoble, Veurey-Voroize, Tullins and Brézins, and in La Forteresse there's farm cheese. There's nothing on the Chambaran hills, so fill up on water in Tullins.

What the journey will cost you

Budget 60 to 100 € a day for a room, dinner and breakfast; Grenoble is pricier than the villages, according to Camino Ninja's estimate (as of October 2026). At the accueils jacquaires you pay by donation, which usually covers dinner and breakfast. The ARA lists the pilgrim rate for bed and breakfast in Tullins at 35.50 €, but that figure dates from 2020; expect more today. For three stages, that comes to roughly 180 to 300 € in total.

Getting Here

• Getting to the start: Grenoble station, with TGV from Paris and TER trains from Lyon, Chambéry and Valence; from there it's about a 20-minute walk to the cathedral. Grenoble-Alpes-Isère airport isn't in Grenoble but near Saint-Étienne-de-Saint-Geoirs, only about 1.7 kilometers off the route; Lyon Saint-Exupéry is usually more convenient.
• Joining partway: Tullins-Fures station on the TER Grenoble–Valence line, on the route at km 28.4.
• Getting home from the finish: Gillonnay has no train station. From La Côte-Saint-André, regional buses run to Grenoble and to nearby stations such as Le Grand-Lemps.
