Overview

The Dão Rail Trail – officially Dão Eco-Trail – follows the route of the old Dão Railroad, which connected the Santa Comba Dão Valley to Viseu until the 1980s. Since 2007, the route has been converted: paved, flat, and open to pedestrians and cyclists. At 49 kilometers, the Ecopista do Dão is the longest of its kind in Portugal.

For pilgrims, the route is an elegant solution: Anyone traveling on the Portuguese Coastal Way or the Central Portuguese Way is on its way and to the Via Nascente or the Interior Portuguese Way Those who want to switch routes can take the Dão Rail Trail as a connecting route through the heart of Portugal.

What makes it special: Railway lines are naturally flat. This makes the route ideal for beginners, for people with knee problems—or for anyone who wants to take it easy after several strenuous days of pilgrimage.

Other Names

• Dão Eco-Trail – the official Portuguese name
• Dão Greenway – occasionally referred to as such in the English-speaking world
• Old Dão Railway Trail – descriptive everyday name in travelogues

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

Ideal, If you need a day of pilgrimage that feels like a rest day: flat terrain, easy navigation, beautiful scenery, and no stress. It’s also perfect for pilgrims who want to switch from one main Portuguese route to another.

Less suitable as a standalone pilgrimage route not connected to a larger route. Even those who wish to make a pilgrimage exclusively on officially certified St. James’ Ways will not be eligible for a Compostela here.

Route & Landscape

The trail begins in Juniper, a small town near Santa Comba Dão in the Mondego Valley. From here, the Ecopista follows the course of the Dão River northward—a tributary of the Mondego, which gives its name to the valley and the wine.

The first few kilometers wind through the typical river landscape of central Portugal: pine and eucalyptus forests alternate with vineyards and small wine estates (quintas). The Dão Valley is known for its red wine—the Dão DOC is one of Portugal’s most renowned. In the spring, wildflowers bloom on the embankments.

After about 25 kilometers, you'll pass Come here, the largest city along the route—a great place for a lunch break or an overnight stay. The last few kilometers lead into the old town of Viseu with its impressive Romanesque cathedral and lively historic center.

Stages, Terrain & Difficulty

The trail can be hiked in one long day (49 km, about 10–12 hours on foot) or, more comfortably, in two days. The natural stopover point is Come here (about 25 km from Vimieiro).

• Vimieiro → Tondela: approx. 25 km, ↗ 130 m, approx. 5–6 hours
• Go to → Viseu: approx. 24 km, ↗ 150 m, approx. 5–6 hours

The surface is paved throughout. There are no significant inclines—the maximum gradient of the old railroad line was less than 2%. The path is easy to walk on, even in the rain.

The Old Railroad Line: History and Character of the Trail

The Dão Line was a narrow-gauge railway built in 1890 and gradually decommissioned by 1988. The route followed the river for over 50 kilometers—featuring two tunnels, a large iron bridge over the Dão, and several viaducts. Today, these engineering structures are the most distinctive features of the route.

The first tunnel is located just past Vimieiro and offers a brief, pleasant respite from the heat on hot days. The large railroad bridge Right in the middle of the route is a classic photo spot: a bird's-eye view of the Dão, with vineyards to the right and left, and the valley stretching out in all its breadth.

What sets this trail apart from many other pilgrimage routes is that it’s quiet. There’s no car traffic, hardly any towns along the way—just nature, the river, and your own pace.

How Hikers Find Their Way to This Trail

You can get there via Viseu (bus from Lisbon/Porto) or Santa Comba Dão on the Lisbon–Guarda rail line. The Rail Trail is not part of the Way of St. James, but it lies exactly within the corridor of the Via Nascente– Anyone traveling that way can take the old railroad right-of-way as a more leisurely route.

Continue the pilgrimage?

And Viseu You have several options available: The Interior Portuguese Way runs through Viseu and continues north toward Braga or Porto.

The Via Nascente It officially begins in Tavira and winds its way through all of Portugal—its northern section passes through the Beira region; you can join the route in Viseu.

Anyone heading toward Saint James of Compostela If you'd like to do that, the best way is to take the bus from Viseu to Porto and then transfer there to the Central Portuguese Way or the Portuguese Coastal Way one—both are about 240 kilometers from Porto to Santiago.
