Overview

On November 24, 1890, the first official train ran from Santa Comba Dão to Viseu, with brass bands and the Minister of Public Works on board: Tomás Ribeiro, a poet from Parada de Gonta near Tondela, who got to open the railway of his home region. For almost a hundred years the meter-gauge Linha do Dão connected the highlands with the main line to Lisbon; the last passenger train ran in September 1988. Since then Viseu has been considered one of the few district capitals in Western Europe without a rail connection. The railway came back anyway—as a footpath.

Between 2007 and 2011 the municipalities of Viseu, Tondela, and Santa Comba Dão turned the line into the Ecopista do Dão, opened on July 2, 2011. That makes the Dão Rail Trail a path of gentle gradients: a steam locomotive can't handle steep ramps, and you feel it in every kilometer. Honestly, it isn't a Camino in the strict sense but a well-built recreational trail—yet one that, between Tondela and Farminhão, runs exactly where pilgrims from Coimbra are heading to the Camino Portugués Interior.

Other Names

Officially the trail is called the Ecopista do Dão, named after the river and the former Linha do Dão. Since the Ecopista do Vouga was extended onward from Viseu in 2023, the region markets the two together as the Ecopista do Dão e Vouga. In English you'll read Dão Rail Trail or Dão Greenway; Portuguese people simply say "a ecopista."

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

Ideal if you're looking for a calm way to ease into walking, want to spare your joints after tough stages, or would like to get to know Portugal away from the coast. Also ideal if you're coming from the south, heading via Tondela to Viseu, and want to make the feeder route to the Camino Portugués Interior easier: as far as Farminhão you have safe, car-free ground under your feet.

Honestly, though, it's not for you if you're after footpaths, forest floor underfoot, and a pilgrim community: the surface is paved, the trail runs dead straight for long stretches, and you'll rarely meet fellow pilgrims here—cyclists and joggers, more likely. Not for you if you're working toward the Compostela, because the Ecopista alone doesn't count. And not for you at midday in July and August: the heat sits in the Dão valley, and shade comes only in patches.

Route & Landscape

Vimieiro to Tondela (km 0–20.5): The trail begins in Vimieiro, the village where Santa Comba Dão's station sits on the Beira Alta line. Via Vale Mimoso (km 1.5) and Quinta do Rio (km 2.8) the trail descends into the Dão valley; at Póvoa João Dias (km 6.5), at 130 meters, you're almost at the lowest point. Then the long, barely noticeable climb begins: Mouraz lies a kilometer off the trail, and via Póvoa de Rodrigo Alves (km 16.3) you reach the level of Tondela, which sits a good kilometer from the trail at km 20.5.

Tondela to Viseu (km 20.5–50.4): Via Valverde (km 22.2), Tojal do Moinho, and Canas de Santa Maria (km 25.6) the trail climbs through wine country and pine forest onto the Viseu plateau. At Farminhão (km 33.4) the Camino Portugués Interior branches off to the north. The Ecopista stays on the railway embankment and runs via Torredeita (km 37.7), Mosteirinho (km 39.6), and Vil de Souto (km 41.6) to the outskirts of Viseu; the center with the cathedral lies just under a kilometer away.

Stages, Terrain, and Difficulty

We show the route in 2 stages. Kilometers come from the Camino Ninja map, calibrated exactly to 50.4 km; staying overnight in Tondela costs you a good kilometer of detour each way.

1. Vimieiro → Tondela (20.5 km) — Down into the Dão valley, then gently uphill; few places to stop for food, a detour of just over 1 km into town.
2. Tondela → Viseu (29.9 km) — Long but steady: via Canas de Santa Maria and Farminhão onto the plateau, arriving on the outskirts of Viseu.

If you need shorter days, split the second stage—but accommodation between Tondela and Viseu is scarce, so plan ahead. The surface is paved, gradients stay at railway level, and tunnels and old bridges are walkable. The real challenge is monotony: kilometer after kilometer of the same rhythm, the same surface. On foot, 30 kilometers on asphalt are a different thing from 30 kilometers of forest track—bring good shoes with cushioning.

The Biggest City Without a Train Got Its Railway Back—as a Footpath

The Linha do Dão was a child of railway fever. A law of January 26, 1876, provided for a narrow-gauge line to Viseu, and in 1885 the newly founded Companhia Nacional de Caminhos de Ferro took over the concession. On June 1, 1890, the first train reached Tondela, and on November 24 the line opened all the way to Viseu, "animada por bandas de música"—accompanied by brass bands, as the chronicles record. Six locomotives from the Esslingen engine works pulled the trains, seven bridges were supplied by the Belgian Société Internationale de Braine-le-Comte, plus the Fonte de Arcada tunnel and the Ortigueira viaduct. In 1937 the line carried 132,273 passengers.

Then came the road. In September 1988 the last passenger train ran, in the late 1990s the rails were torn up, and Viseu became a city the Portuguese like to call "a maior cidade da Europa continental sem comboio"—the largest city in continental Europe without a train. The first section near Viseu opened as an Ecopista in 2007, and on July 2, 2011, the whole route was finished. The track bed became a trail on which the kilometer markings now run in the opposite direction from the old railway.

What this means for you: railway engineering is your signpost. Watch for the old station buildings, signal posts, and kilometer stones that survive in many places. And for a lovely irony: pilgrims walking from Coimbra to Viseu board, in a sense, a train at Tondela that hasn't run since 1988—and get off again at Farminhão.

Highlights Along the Way

• Santa Comba Dão station in Vimieiro (start) — a station on the Beira Alta line, opened in 1882, and from 1890 to 1990 the junction for the Linha do Dão; António de Oliveira Salazar, the later dictator, was born in Vimieiro in 1889, and he is buried here.
• Dão valley (km 6.5) — the lowest section, with the river and the old railway bridges, plus vineyards of the Dão wine region.
• Tondela (km 20.5, 1.1 km off the trail) — a county town with hotels, restaurants, and the heritage of the old Concelho de Besteiros, which existed until 1836.
• Capela de Valverde (km 22.2) — a chapel from 1600, one of the oldest monuments in the municipality of Tondela.
• Canas de Santa Maria (km 25.6) — the 12th-century Igreja Velha de Santa Maria, its facade protected as a National Monument; the village was called Canas de Sabugosa until 1966 and has been a vila since 1997.
• Farminhão (km 33.4) — old station, rest stop, and the point where the Camino Portugués Interior branches off; birthplace of Capitão Leitão, one of the leaders of the republican uprising in Porto on January 31, 1891.
• Cava de Viriato (outskirts of Viseu) — an octagonal earthwork 2 kilometers around, a National Monument since 1910; it only got the name of the Lusitanian leader Viriathus in the 16th century.
• Sé de Viseu and Museu Nacional Grão Vasco (center, just under 1 km off the trail) — a cathedral begun in the Romanesque style in the 12th century, with a Manueline vault and a Renaissance cloister; next door, the museum founded in 1916 with the panels by the painter Vasco Fernandes that once adorned the cathedral's high altar.

How Pilgrims Find Their Way onto This Path

Most walkers and cyclists start at Santa Comba Dão station or in Viseu. Pilgrims typically join the trail on the feeder route from Coimbra via Penacova and Mortágua to Tondela: from there they follow the Ecopista as far as Farminhão, where the Camino Portugués Interior—which begins a few kilometers earlier on our map—leaves the trail and heads via São Cipriano to Viseu.

If you walk the whole Dão Rail Trail from Vimieiro, you add a calm prelude before the Interior. Since there's no pilgrim infrastructure here like on the Camino Francés, plan your overnight stays in advance.

Continue the pilgrimage?

Yes—and properly. In Farminhão, or in Viseu at the latest, the Camino Portugués Interior begins: over the Serra do Montemuro to Lamego, across the Douro at Peso da Régua, through Vila Real and Chaves to Verín in Spain, where it connects onward toward Santiago. From Farminhão to Viseu you can choose: the pilgrim route via São Cipriano or the Ecopista via Torredeita.

Honestly, the switch is a step up into a different league: the Interior is mountainous, the stages are long, and the elevation gain multiplies. The rail trail is then your last flat stretch for many days.

Preparation & Practical Information

Pilgrim passport and app. The Ecopista isn't an official Camino, and you can't earn a Compostela with it alone. But if you're continuing on the Camino Portugués Interior, a pilgrim passport (credencial) is worth having from the start: you'll get stamps in cafés, churches, and lodgings, and in the end the route counts toward the Compostela as long as you walk the last 100 kilometers to Santiago. It's best to order it online in advance so it reaches you in time for the start of your trip. In the Camino Ninja App you have the map and track offline; the easiest way to plan the route is right in the app, where you put your stages together and plan suitable accommodation along with them.

Water, shade, bikes. You share the Ecopista with cyclists, so keep to the right and expect oncoming traffic. Not every old station has drinking water—carry enough, especially in summer. In spring the embankments are in bloom, and in fall it's grape harvest season in the Dão region.

What the journey will cost you

The Ecopista itself is free. In Viseu the youth hostel charges around 16.50 € for a dorm bed and 30 € for a private room, and hostels run 20 to 25 € (as of October 2026). Tondela and Santa Comba Dão have hotels and guesthouses, where a double room usually costs between 40 and 70 € (as of October 2026).

Budget 35 to 50 € a day including simple lodging, breakfast in a café, and a set lunch menu—inland Portugal is cheaper than the coast. Bus and train fares to get there and back are usually under 20 € (as of October 2026).

Getting Here

To the start. Santa Comba Dão station in Vimieiro is on the Beira Alta line between Coimbra and Guarda; before you travel, check whether trains or replacement buses are running after the line's renovation. Bus connections from Coimbra and Lisbon also reach Santa Comba Dão.

From the finish. Viseu has no train station, but it has a central bus station with connections to Porto, Coimbra, and Lisbon. If you're continuing on the Camino Portugués Interior, you simply set off on foot.
