The Roof of the Cévennes (by mountain-bike)
The Tarnon valley is shaded by the old beech groves of Le Marquairès state forest. At the Col de Salidès, views open up onto the characteristic landscapes of the National Park. In the distance, flocks of sheep still graze on the limestone plateau of the Can de l'Hospitalet sitting on its schist platform.
Hermit beetle (Osmoderma eremita)
This beetle is a declining, endangered and protected species. It is considered a reliable bio-indicator of environmental quality. An essential link in the proper functioning of forest environments, it likes mature deciduous forests and dead wood. The specific management of the strict nature reserve of Le Marquairès favours its development. Here, forestry is forbidden, and the forest is left to evolve naturally.
1938: the forestry road
The Tarnon is 38.9 km long and has its spring on the Aigoual massif (1,565 m) in the municipality of Bassurels. After its confluence with the Mimente, it flows into the Tarn downstream of Florac. It separates the Causse Méjean plateau from the Cévennes. Upstream of Rousses, the Trépalous flows into the Tarnon. This small river has carved out the Tapoul Gorge, which is famous for canyoning. The Tarnon is a Cévenol river: very abrupt and intense floods can occur during extreme weather events.
The Margeride draille (drovers’ road)
The draille follows the ridge and crosses the Can de l'Hospitalet plateau. This transhumant trail enables the sheep flocks of the plains (of the southern Cévennes and the Crau) to move up to northern Gévaudan (Aubrac, Margeride, Mont Lozère). This draille is only one branch of a larger network along which transhumant livestock still travel.
A beautiful view onto Mont Aigoual (1,567 m) – a mountain of winds, fog, snow and rain. Banks of clouds coming from the Mediterranean rub against its slopes and can cause violent precipitation (also called Cévenol episodes). This temperamental mountain is home to the last mountain weather-station in France.
Mountain-bike route #14. From the village, take the D 907 for 4 km towards the Tunnel du Marquairès. Before the tunnel, fork right towards Le Marquairès forester's house and continue on the forestry track to Gaseiral. Take the road uphill to the Col de Salidès and there take the ridge track on your left to L'Hospitalet (GR 7). After about 3 km, take the track on the left that leads back to Rousses.
No cycling off-track. You are strongly advised to wear a helmet. Do not forget your repair kit and a small set of tools. Please shut all gates and barriers after yourself. Slow down in farms and hamlets.
