The tour of the Pic du Jalouvre

This tour will undoubtedly allow you to spot ibex, which are often in the area, but also to observe a wide range of alpine flora, including Saint Bruno's lilies, Liotard's stars, soldanellas, and more. With a little luck, you may even spot a ptarmigan or chamois.

Description of the walk

This hike starts at a bend in the road leading up to the Col de Colombière, where there is a small car park with space for a few cars.

(S/E) Then climb up the small path. This small path climbs up a corridor and becomes increasingly steep, crossing a few small scree slopes and rocky outcrops. You will arrive at the Col du Rasoir between Pic du Jalouvre and Pointe Blanche. As its name suggests, this pass is as sharp as a razor blade...

(1) The descent opposite is just as steep and takes you down a scree slope. At the start of the season, there may still be snow, in which case you can descend by scrambling.

(2) Pass under the Dents du Jalouvre and turn left to reach the Col de Sosay.

(3) From the pass, you will see Lake Lessy with houses around it. Descend in this direction on the trail.

(4) Pass the Chalets de Lessy and go around the lake on the right, leaving it on your left, and climb towards the Col de la Forclaz, always taking the path on the left without descending.

(5) Once at the pass, turn left onto a small, gently sloping path that will take you across a scree slope and the side of the Aiguille Verte. You can still admire Lake Lessy. When you reach the path that goes around the lake on the other side, the path climbs to the right to cross the ridge at Co.

(6). The descent is quite steep through the mountain pasture. Keep following the path that turns to your left to reach the foot of a Via Ferrata.

(7) Continue on and, after a long traverse under a large rock bar on the side of the Pic du Jalouvre, you will return to the car park (S/E).

The route was completed in mixed weather, with very foggy conditions at the summit of the Col du Rasoir. The last few hundred metres are a little technical and it can be difficult to see the path due to poor visibility (we missed two cairns when crossing the rock slab), but by checking the route on Viso Rando, we managed to get back on track and reach the summit. The descent to the Col de Sausay is also technical (the ground is sometimes unstable) on the first third, then becomes very pleasant, as does the junction at the pass and the descent to the lake. The rest is almost a formality.

The route was completed today in near-perfect weather conditions. We made a few detours that I would recommend: climbing Pic de Jalouvre (but with some icy sections), the ridge line towards Col de Sosay (point (3)), and the ridge line towards Col de l'Arête (point (7)).
The scenery was magnificent with fairly good visibility (particularly the Aravis mountain range and Mont Blanc)
During the climb, we spotted a few chamois (but they caused some rocks to fall... be careful!).

Many thanks to the author of this description.

Note: at point ::8: there is no other path crossing the slope, so this point of interest does not seem to be justified.

A superb loop that is quite difficult due to the Col du Rasoir (steep scree on both sides requiring good Vibram-type soles). I just managed it with my low hiking boots because the route is poorly marked from the Col de la Colombière to just below the Col du Rasoir. Then the red arrows were random because apparently the route changes from year to year. We climbed straight up the slope in the middle of the pass, then crossed over to reach the final fault line. At this point, a girl above us started to slip, which blocked my partner Laurence. Two local guys who were coming down kindly helped her. Thank you to them! The descent on the other side is less steep but tricky. It is better to descend to the small lake and then climb back up to the pass to reach Lake Lessy, as the upper traverse path is rubbish and under the Jalouvre wall. To make the end of the route easier, it is better to pass under the green needle rather than descend into the mountain pastures via the steep path described. Do not attempt in wet or snowy weather!!! 5h45 as announced

We were afraid we wouldn't find the starting point of the hike, but the instructions were clear. When we arrived at the Col du Rasoir, we lost the path and the last few metres proved a little perilous, but overall the climb to the pass is easy. The view from the pass is superb, and the detour to the Pic du Jallouvre can be done quickly. Once you've descended the scree slope, the hike becomes much easier. We went in the afternoon and encountered parish specific to Brittany during the second half of the afternoon!

The hike starts off steeply! At the Col du Rasoir, it's quite exposed, a feeling accentuated by strong winds yesterday. Not recommended for children.
The trail can sometimes be less clearly marked, so you need to stay alert. The descent on the Cenise side via Lac de Lessy is also rocky. The Col de Sosay is magnificent. Lac de Lessy remains very popular because it is more easily accessible from Le Petit Bornand.
The descent below Buclon towards Chinaillon is steep at the beginning. A very beautiful hike that takes about 5 hours at a leisurely pace.

A little hesitation at the beginning, to join the route starting from the pass.

At the Col du Rasoir, I couldn't resist crossing over to the Pic du Jallouvre. Back at the pass, the scree slope was criss-crossed with several paths. Study the route carefully, as not all the paths are complete and some require extra effort. Exceptional views, a rich and enjoyable circuit. Very busy around the lake. Thank you

The climb up the Col du Rasoir is quite difficult because it is on scree. Once you reach the top, don't look behind you because it can be quite daunting. The descent from the Col du Rasoir on the other side can be a little nerve-wracking as it is over scree with few handholds and the path is barely visible except for the last few metres to the other pass leading to Lac de Lessy. Watch out for falling rocks on this section! After that, it's pure bliss with views of Mont Blanc and encounters with ibex. I completed the route in 4½ hours on my own (not recommended) in glorious weather.

The schedule can be reduced to 6 hours with a 30-minute picnic at Lake Lessy
Beware of rockfalls when climbing the Col du Rasoir (they are constant)

With great weather, the anti-clockwise tour of Pic de Jallouvre as suggested is perfect.
The description provides all the information you need, including the degree of difficulty.
It is worth mentioning that there is a risk of being hit by falling rocks if a group is ahead of you and you do not keep a safe distance.

A beautiful hike through the forests of Ardèche, ending at the summit of Le Gerbier with its magnificent view of the knoll and the plateau.

A hike that promised to be great. Too bad there was too much snow! We had to turn back at the Col du Rasoir on Friday, 14 April. But the scenery was beautiful... a route to do again as soon as possible!

Hike completed last week in 6 hours (including a 30-minute break at Lac de Lessy).

The hardest part is reaching the Col du Rasoir because the scree slope is quite steep. A little tip: use your hands to help you, don't stick too close to the person in front of you as this will make the terrain even more unstable, don't look behind you, and you'll get through it! This part can be a little nerve-wracking as there are few or no handholds, so try to keep a steady pace as stopping will make it more difficult.

Once you reach the Col du Rasoir, enjoy the magnificent view with Mont Blanc in the background – it's superb! Now you have to descend the other side, and strangely enough, there's another scree slope... Descend on your heels, you'll slip much less. Once you've passed this slightly unpleasant section, you won't encounter too many more difficulties. The snack break at Lake Lessy is very pleasant, with lots of cows keeping us company.

Take walking poles to relieve your knees and enjoy!
