La Bosse de Clapouse

This early morning hike is a sure-fire way to see chamois. It is easy to access and well-equipped photographers will be able to take some beautiful shots. For everyone else, the views alone will be a feast for the eyes.
The only difficulty is getting up very early

Description of the walk

The trail starts from the car park at the end of the road behind the Ailefroide campsite, which is very small.

(S/E) Set off at dawn, or even earlier, as the path is not tricky. Head to the bottom of the car park, following the usual signs.

(1) Turn left, following the signs for the Sélé and Pelvoux refuges. The trail is in the woods.
after 800 m, with very little climb (100 m), you will reach a fork in the path.

(2) Turn left to cross the footbridge that leads to Clapouse, leaving the paths at the bottom of the Vallon du Sélé on your right, which lead to the two refuges. Take the well-marked path that starts to climb quite quickly. There are no particular difficulties, but you need to start paying attention.
Chamois are likely to be nearby and will move away. Do not startle them; keep an eye on their movements.
Do not stray from the path, as there are some rocky outcrops on your left as you climb.
Climb up to the hump just below the 2,200 m mark, a 600 m climb. You can stop and take a look around.

(3) Begin the descent via the same route to return to the car park (S/E).

Practical information

A headlamp is useful if you want to set off before dawn.
High-top hiking boots (for scree), walking sticks (not essential), cap and sunglasses.
Bring a camera and binoculars.

(3) If you keep your eyes peeled, you may see them arriving below you, coming from the Alpe de Clapouse, climbing up the scree to reach the valley.
As the morning progresses, the chamois will climb higher up the valley. You can wander freely throughout the area, including towards the Alpe, but there are no trails.
Once the "hunt" is over, enjoy the scenery and have a snack in the area.

You are hiking in the heart of the Ecrins National Park.

The Écrins massif is an exceptional area, open to all, with a rare natural, cultural and landscape heritage. To protect these treasures, the heart of the park is marked by blue, white and red flags, where regulations must be observed.

Hike dedicated to spotting chamois and possibly marmots.
The view is splendid, the hill is accessible to children and very pleasant.

Moderately pleasant climb with lots of scree, to be avoided if you have weak ankles, but the final view is absolutely magnificent and well worth the effort

An excellent start to the day, leaving the campsite early in the cool morning air.
we spotted 11 chamois in the Alpe de Clapouse with binoculars after waiting for the clouds to clear!

A must-do hike in this area.
The view of Pelvoux and the Clapouse valley from the Clapouse hill is superb, especially as the ground is grassy at the top.
You can continue on to the bottom of the valley.
Today's route takes you over the new Himalayan footbridge, which is lower than the crossing indicated on the trail. Its height will probably prevent it from being destroyed during the next flood.
There are some steep sections, but these do not pose a problem for people in good physical condition.

First of all, thank you very much for this itinerary.
We set off at 5:30 a.m. and were completely alone until we reached the hill, where we met a few people climbing up as we were coming down. A superb itinerary, with a good but gradual elevation gain. A few sections are a bit steep, as is the footbridge at the start, but it's doable, fairly safe and definitely worth it!
three-quarters of the hike is shaded and full of flowers at this time of year (mid-July).
Overall: a dozen chamois, including three very close by, a black grouse (what luck!) and a marmot!
Thanks again.

Hike completed in mid-August 2024. We started the trail at 9 a.m. with two children aged 5 and 8.
Please note that the car park is very small, with space for no more than 10 cars. However, you can park nearby in Ailefroide.
The start is gentle, followed by a very fun section for children with a superb footbridge and rock crossing with cables. The climb is then very consistent, in the shade. There are no particular difficulties. It takes 2 hours to reach the hill.
We didn't see any chamois. However, there are quite a few wild strawberries at the start of the route, lots of wild raspberries in the first part of the climb and finally an abundance of blueberries at the top.
There were few people on the trail. We were only a handful of hikers at the top. It's a wonderful place for a picnic. You're surrounded by peaks over 3,500 metres high, including Pelvou.
It's a really beautiful hike to do with the family.

Very beautiful route, a bit steep in places but the vegetation is magnificent (in July), allowing for plenty of photo stops!
The route is fine, except for finding the starting point "behind the campsite"... After that, it's a round trip, so you just have to follow the path! (Despite the late hour, around 10:30 a.m.), we saw a rather tame chamois that let us take its picture!

A lovely walk, as always. The paths were quite wet following the night's storms. The peaks were shrouded in clouds. A shame about the view. Note that a new footbridge has been installed downstream from the old one. The rest of the route crosses rocks equipped with cables, which are probably only used to help walkers navigate the boulders as they serve no other purpose.

A beautiful hike offering lovely scenery and a glimpse of some of the Écrins glaciers. The footbridge was replaced in May 2022 (moved further downstream from the old one) and is worth the detour alone (a 27-metre suspension bridge between two trees). The new path after the footbridge requires scrambling between rocks before rejoining the original trail. This is followed by a beautiful walk through raspberry bushes before a second, steeper climb. The climb is mostly shaded.

A few people at the finish, and a glimpse of a chamois through binoculars. Hike done with two children aged 6 and 8. Departure at 9:45 a.m. for arrival two hours later.

Parking spaces are limited at the start, so arrive early (before 9 a.m.)!

Hike completed on 12 August: it is possible to use the footbridge located just downstream from the one that was washed away by the torrent, and then climb up the opposite bank to the one suggested in the hike description. There is a path at first, then you have to scramble a little among the rocks, but it's not difficult, especially as cairns mark the route.
A magnificent hike, and a mountain goat waiting at the finish line, despite the late hour (1 p.m.!)

An official sign in the Écrins National Park indicates that the trail is "temporarily closed." This is probably due to the absence of a footbridge, and it was very risky to cross the torrent today given its flow.
We therefore continued along the very pretty trail towards the Pelvoux refuge

At the end of July 2021, the footbridge is still broken and impassable. It is best to cross at the start of the walk.
We continued on to the refuge. The walk is pleasant early in the morning, and we saw five chamois.
