Description of the walk

The walk starts at the car park located at a hairpin bend on the D53 just before reaching the village of Théus (Hautes-Alpes) from the Durance valley.

The entire route is marked with yellow PR® signs.

(S/E) Leave the car park and cross the stream to reach a junction immediately. Turn left and follow the path uphill, crossing the stream several times via small footbridges.

After about a kilometre, you will begin to see the first formations of the Demoiselles Coiffées (also known as the Cheminées de Fées), to the left and right of the path. You will emerge onto the Route du Mont Colombis (D53a). Turn left for a final view of the Salle du Bal des Demoiselles Coiffées and the Durance valley. Continue to a picnic area located about 100 m away.

(1) Return to the D53a by heading up to the right and follow it for 3.5 km.

(2) For the last kilometre, veer slightly off the road by cutting right through a small pine forest dotted with numerous anthills. Return to the road and continue to the right.

(3) After the first set of pylons, leave the path on your right (which you will take on the way back) and head towards the Croix Choureille. The view makes the 3 km of tarmac well worth it.

(4) Return to the road.

(3) Take the path on the left running alongside the fence of the antenna building. Head straight down, due south, along the Échine de l'Âne.

(5) At the junction, continue straight on. Keep to the right at the next junction and begin a series of hairpin bends.

(6) Ignore the path on the left leading to Noutaret and continue to the right. The final bends take you back to the ford and then to the car park where you started (S/E).

A lovely little circular route with the unique geological features of Les Demoiselles Coiffées and a beautiful view from the top of Mont Colombis. It's a shame, however, to have to endure more than 3 km of tarmac at the end of the climb, even if the road was quiet that Sunday. The descent is sometimes tricky but fun. Towards the end, once you reach the abandoned house in the middle of a meadow, the route signage is missing. You should leave it on your right, cross the orchard and head towards the forest to find the marked trail again.

What a lovely find this geological site is, with stunning 360° views from Mont Colombis and a lovely descent along the ‘Donkey’s Back’ ridge (it’s a shame about the tarmac section, but it’s hard to avoid – fortunately, we didn’t come across many cars).
Thank you for sharing this.

Hike completed with a slight variation in 2015.
I made a video with the names of the peaks, which largely shows the route and the atmosphere of the walk.
