A lovely walk offering great variety in terms of the surroundings and the paths taken: marl, cliffs, forest, viewpoints and steep riverbanks.

Description of the walk

The walk starts from the hamlet of Saint-Genis in the commune of Garde Colombe.
From the D1075, between Laragne and Serres, take the D94 and park near the town hall annexe, just before the village of Saint-Genis.

(S/E) With your back to the car park, turn left towards the Gorges du Riou. Continue along the road and cross the hamlet: note the sundial opposite Saint-Jaume Church.

(1) Continue along the D94 and stay on it, ignoring the small road on the left. At the next Fork in the road, turn left. At the top of Saint-Genis, you will find a path marked in yellow and red. Follow the signs for the Gorges du Riou and, after about 30 minutes’ walk on virtually level ground, you will come to a stone bridge on the right.

(2) Ignore the return path ahead, cross the Torrent du Riou and walk along the left bank. The path soon climbs in wide switchbacks (a few yellow markings). After about half an hour’s climb, you’ll come to a wider forest track. Take it to the left for about a hundred metres to reach the Route Forestière du Château.

(3) Turn left onto it. Continue through the forest, passing the Source du Château. The forest road winds through several bends to the left and right before reaching a junction just after a final right-hand bend.

(5) Turn left towards the Gorges du Riou (signposted). Enjoy some stunning views before descending to the bottom of the gorges.

(6) At the bottom of the descent, go through a tunnel and then cross the Riou on a wooden bridge. Then turn left along the gorges to return to the stone bridge you crossed on the way there.

(2) Follow the path you took on the way there in the opposite direction to Saint-Genis, then on to the town hall car park (S/E).

Hello,
I did this hike on Sunday, but in the opposite direction. You walk up the Riou Gorge, which offers beautiful views with the autumn colours. We had a picnic at the Riou lake on the way back from the hike.

Very good hike. The climb is steep for 20 minutes after the bridge, but once you reach the forest path, there are lots of other hiking trails signposted. The descent into the gorges is very beautiful. My dog was able to swim before and after the hike.

I can’t get hold of anyone at Visotando!! I’ve been having problems for months with the elevation profiles not showing up!!! And my emails always go unanswered!!!! And for months I haven’t been able to save my new hikes!!!! And I never have the option to stop the route simply by pressing a button... stop! I’m forced to log out of Visotando!!
And never a reply, never any advice!
