Description of the walk

Start from the hamlet of Moulin de Cost.

(S) Cross the field behind the campsite and join the road (D72). Continue for about 100m along the road (to the right).

(1) Take the forest track on the left. 400m further up, ignore the path on the right and continue along the forest track, which climbs steadily up to the pass.

(2) From the pass, ignore another path on the right and continue down the forest road.

(3) At the junction, turn left. You’ll catch glimpses of Buis-les-Baronnies from time to time. The descent is very gentle until you reach the tarmac road.

(4) Follow this road to the left for about 50 metres, then join the D72. Turn left and follow the D72, which takes you back to the hamlet of Moulin de Cost (E).

A very short walk to get out and about whilst dodging the rain on a rainy day. The start, near the campsite, isn’t signposted, nor is the forest track. The return journey, along a fairly busy road, is, in our opinion, a bit risky. A walk of little interest.

From WP1 to WP4, the walk is pleasant, the elevation gain is manageable – even with children – and the path offers some lovely scenery. However, the section that includes the RN stretch (i.e. the out-and-back section) is quite tricky. The mill has a restaurant and a bar where, it seems, you can have a drink, but the section after that runs right through the middle of the campsite, and if you’re not staying there, it’s considered rude to cut right through it. The RN is quite busy and is rather dangerous as there are three blind bends. If you’re adults and experienced, no problem; if you have children, it’s more complicated. There’s a place to park near WP1, at the end of the access road.

To park, do so at the junction with Cost (there’s space either before or after the bins) and follow the route in the opposite direction.
