Old Lamastre train station

Highlight • Historical Site

The old Lamastre station is the arrival point of the Ardèche train. Called Le Mastrou, this train takes you on a discovery of the Gorges du Doux. Built from 1886 to 1891, the railway line goes up the gorges from Saint-Jean-de-Muzol to Lamastre. This old steam locomotive takes you back in time. It is possible to make the trip with bicycles. Remember to book your tickets well in advance, especially during the summer.

Trail along the Sumène

Highlight (Segment) • Trail

This path runs along the Sumène, a small river that can sometimes be glimpsed among the trees. This section alternates shaded parts with segments in full sun, just to vary the pleasures!

Nonières Tunnel

Highlight • Cycleway

The great thing about old railway tunnels on a cycle route: They often save you a tedious road over a pass. Although you sometimes lose a bit of a good view, a trip through a tunnel is still a very special and, on a hot day, particularly refreshing experience on a bike tour. This tunnel is even illuminated and, at 320 metres, is the longest on the entire Dolce Via.
