Aiguillette des Houches from La Flatière

The Aiguillette des Houches dominates the valley on the sunny side. The circuit offers exceptional views to the west towards the Assy plateau and the Saint-Gervais and Combloux valleys. To the south, the view covers the entire "Mont Blanc crossing" route: Aiguille du Goûter, Dôme du Goûter, Mont Maudit, Mont Blanc du Tacul and Aiguille du Midi. In the valley, every chalet in the village of Les Houches can be seen. The route is fully signposted. The loop described here starts from the hamlet of La Flatière, at an altitude of 1,370 metres. It is not new but offers a choice of possible options. The ascent is via the most direct route. It takes 2 hours and 20 minutes at a mountain pace. The first half is in the shade. From an altitude of 1,987 metres, the path follows a ridge that is both steeper and more exposed. If you set off in the middle of the morning, you will reach the summit around midday. The descent is more gradual.

Description of the walk

Drive from Les Houches station along the Coupeau road to the hamlet of La Flatière. Park along the road at the entrance to the hamlet.

(S/E) Follow the road up through the hamlet of La Flatière to the entrance gate of the Foyer de la Charité

(1) Take the path on the right to Plan de la Cry.

(2) Turn left, north-west, onto the shortest route. Follow the signs to Aiguillette des Houches, always choosing the shortest route. As you climb, an exceptional view gradually opens up towards the lower Arve valley on your left. Reach the Pierre Blanche at an altitude of 1,697 metres.

(3) Turn right, continuing to follow the arrows towards the Aiguillette until you reach the top of the ridge.

(4) Go around the Petite Aiguillette des Houches, leaving it on your left. A traverse then leads to the foot of the final climb to the Aiguillette. During the traverse, you may need a walking stick to safely negotiate a few sloping sections and reach the summit of the Aiguillette des Houches (breathtaking 360° view).

(5) For the descent, follow the route south via the Chalets de Chailloux.

(6) Continue opposite, south-west, to the Plan de la Cry, which you passed at the start of the hike.

(2) Finish the descent by following the same route as on the way up to reach the (S/E).

Notes

Equipment for hiking in the mid-mountains. Walking sticks provide extra safety on the sloping path between (4) and (5) and make the descent more comfortable.

Be careful of the temperature at the summit, which is typically 8° lower than in the valley. Take into account wind exposure, which can make it feel much colder.

The bivouac can bebooked here.

This route passes through multiple protected areas, which may be subject to special regulations:

Worth a visit

On the descent, refreshments are available at the Chalets de Chailloux at an altitude of 1,913 metres.

In my opinion, this is one of the most beautiful hikes in the mountains, offering unique views of Les Houches, Les Fiz and Le Brévent.
It's a good workout on the way up and a very pleasant descent with a stop at Le Chailloux, a simple and efficient refreshment bar with a beautiful view of Mont Blanc.

A beautiful hike surrounded by autumn colours. We continued along the ridge to picnic a little further on, towards the Pointe de Lapaz. Please note that you need to park at the Bettey car park, just before the indicated starting point.

It climbs gradually on a fairly flat path, then steeply near the summit.
Most of the descent is also easy on flat ground.
I preferred this route to the one that goes via the Belachat refuge as it is easier on the knees during the descent.
However, there is a slightly tricky section at the summit.

9 May 2024, still lots of snow on the route, fabulous scenery! Thank you for this magnificent tour!
With the snow, walking poles were essential, and light crampons would not have been a luxury, especially between points 4 and 5. On the ridge between 3 and 4, there were large seracs, so we veered slightly to the right to avoid exposing ourselves.
When we reached the top, the weather was mild, so we took the time to admire the view...

Aiguille des Houches climbed in winter, with crampons and snowshoes (also possible with touring skis) via Les Chalets de Chailloux, i.e. the route described for the descent.
First, park before Bettey: there are car parks on the left of the road, as access to the village and La Flatière is now reserved for residents. The climb through the forest in frozen snow in the morning justified the use of forest crampons. I kept them on beyond the Chalets de Chailloux, as the snow was fairly firm, but I put on snowshoes for the descent down to the forest, as the snow cover had softened.
Magnificent view from the ridge, over Mont Blanc, Les Fiz...
Quite a few people up to the Chalets de Chailloux, a little less beyond, but it's still a popular area (skis, snowshoes or crampons).
Highly recommended.

Walk completed on 16/09/2023 in good weather.
The climb is pleasant, passing through the forest, which gradually thins out, to the mountain itself.
The difficulty increases but is not insurmountable.
The view is magnificent and it's worth pushing on to the "Pointe de La Paz" for lunch and to take in the stunning scenery.
Of course, you can go even further, but you have to think about the descent, and that's where the trouble starts.
No, I'm exaggerating, but it's not pleasant at all, as is often the case in the mountains. You can't have everything.
You have to hold on to the good memories, confirmed by the photos taken by professionals, which are undoubtedly identical to those taken by the thousands or even millions of hikers who came before us, but they are ours.
There you have it

It's always very satisfying to climb up to the Aiguillette to enjoy the panorama and the beautiful colours of early autumn

About the hike to Lac des Verdets today, 2 October 2023. The lake no longer exists; it is dry. The two water sources indicated were not available because the two refuges were completely closed with no access to a tap. Otherwise, the description and map were perfect. In my opinion, the description should specify that the availability of water depends on whether the refuges are open.

Have a good evening.

Start of the hike at 9 a.m. Beautiful weather. We chose the shortest route.
The first part, in the forest, is monotonous and easy. Little by little, the trail climbs and the view opens up! Phew! Valleys, mountains, magnificent.
From "la pierre blanche" (the white stone), the pace changes due to the steepness! And there's the ridge, offering views
. Finally, the summit, with a 360° panoramic view. Our jackets and hats protect us from the cool air!

After a snack, we begin the descent in the sunshine, admiring the Mont Blanc massif.
A varied hike, easy going with a few steep sections, a pleasant discovery.

Hello,
Preliminary note: I preferred this hike to the one at https://www.visorando.com/randonnee-aigu..., which seems to include some vertiginous passages requiring equipment. However, it is an alternative to consider for the more adventurous.

This hike is not difficult. Be sure to bring plenty of water. The first part of the hike is in the forest, which provides some shade but still offers some beautiful views. The signs indicate a 2 hour 20 minute climb from La Flatière to the summit of the Aiguillette des Houches (approximately 900 metres of elevation gain).

At the summit, after enjoying a 360° view, including Mont Blanc and its neighbours, I took a little detour along a ridge path that passes by the Pointe de Lapaz and joins the Bellachat refuge. This ridge path is not difficult and is not vertiginous. The landscape is magnificent. I then returned to the summit of the Aiguillette des Houches and descended via the suggested route (1 hour 20 minutes). The bonus/alternative route I mentioned adds 1 hour 30 minutes and perhaps an additional 200 metres of elevation gain, which are hardly noticeable. At the Bellachat refuge, you can eat and buy water (no drinking water).

Thanks to Étienne for posting this hike, I'm happy to be the first to comment on it.
