The Grand Perron des Encombres from La Saussaz

This hike takes you to the Grand Perron des Encombres, starting from La Saussaz. The access road is narrow but paved all the way to the start of the hike. The view from the summit is extraordinary. An exceptional 360° panorama with Mont Blanc dominating the scene and, above all, the near certainty of encountering ibex.

Description of the walk

Access: To get to La Saussaz from Saint-Martin-de-la-Porte, head towards Beaune. At La Villette, turn left towards Le Mollard. Pass Charbutan and then Les Rateaux; the car park is at the end of the road.

(S/E) Leave the road on the left; the trail begins by descending towards the Chapelle de la Bachellerie in the hamlet of Lechepre.

(1) Leave the main road and turn right onto the path that begins the climb.

(2) When you reach the Petit Col des Encombres, note the nature of the ground. The gypsum seems to have been sculpted by water, which has made circular holes in it. Continue left towards the cross.

(3) Take the path climbing to the left, which is a little longer but has a gentler incline. Leave the shorter but fairly steep path (on the right as you climb), which will be the way back.

(4) This is where the two paths meet. Turn left and follow the path.

(5) If you look towards the summit (north), you will see a herd of ibex on the rocks. Do not disturb them, as they are easily visible. The path slopes northwards and crosses over to the other side

(6) If the ibex were not lower down, you might see them in this area. Follow the climb to the summit, keeping north.

(7) The final section is a little difficult. The path is steep and a little slippery due to the earth and gravel. There is a handrail all the way to the summit. It is welcome, especially for the descent, but there is no danger. Highest point. A cross and, more importantly, an orientation table allow you to name all the surrounding peaks. What a sight!

(8) Return via the same route until you reach the trail junction.

(4) Continue straight ahead on a steeper section until you reach the next junction.

(3) Continue on the same path to return to the starting point (S/E).

Notes

There are no water sources along the way, so remember to bring water.
Walking sticks are not mandatory but can be helpful both on the ascent and descent.
For geocaching enthusiasts, there is a nice little series of caches.

Worth a visit

Don't miss the ibex and persevere to the summit to see the spectacle, you won't be disappointed.
Near the ibex area, you can admire numerous edelweiss flowers.

an easy summit with no difficulties on the Maurienne side, offering fantastic views and a beautiful orientation table at the top.
ibex, marmots and vultures are almost always visible.

A beautiful hike in a wild valley.
Magnificent view and superb 360° orientation table
Hike completed on the Tarentaise side from ST Martin de Belleville. The access road seems long, but it's just that you have to drive at walking pace for 10 km.
The signs were only put up on the day of our hike, 5 August

Magnificent hike.
Reaching the car park by car is not very easy due to the narrow mountain roads and lack of signposts.
But it's well worth the effort.
The cavities described in the gypsum at the small Encombres pass are impressive.
We saw some ibexes – it was the first time we had seen them so close.
The view is breathtaking... a slight disappointment due to the cloud cover, which prevented us from seeing the surrounding mountains.
Highly recommended!

Beautiful hike, but we didn't make it all the way to the end. The ibexes were there waiting for us on the ridge. Thank you for sharing.

Very beautiful hike. Beautiful 360-degree panorama with orientation table. Not much space at the summit. We didn't see any ibex. The last part is steep and should not be attempted in wet weather.

A beautiful hike done in early August – easily accessible except for the last 300 metres, where the climb is quite steep and the ground is loose (luckily there is a cable )
You're almost guaranteed to see ibex in summer. 360-degree panoramic view of the Alps from the summit
I recommend it

A magnificent summit in the heart of my Maurienne region. 360° view.
Encounter with ibex. The last part is a bit steep but equipped with cables.

Very accessible approach trail. Beautiful hike, windy passes. Large wildlife present: ibex near the passes, marmots galore. Very diverse flora. Picnic possible, less windy, shortly before reaching the summit.

Effective signposting in the absence of snow. Magnificent 360° panorama.
Care should be taken with children for about 30 metres above the Petit Col des Encombres.

In addition to the 360° panorama at the summit of Grand Perron, the main attraction of this hike is the opportunity to observe ibex.
Unfortunately, the weather was not conducive to panoramic views and the ibex were not present at the summit, unlike on a previous hike nine years ago when I was able to get very close to a herd of about twenty individuals. However, I did spot a few shortly after the Petit col des Encombres.

.... Hike completed on a Sunday at the end of the school holidays, with the Saussaz car park full. With everyone walking at their own pace and the option to take a different route up, the crowds remained reasonable despite groups of more than 10 people. Beautiful 360° views at the summit, with changing clouds. Vultures, marmots and a few ibex along the route.
