Water sources at the refuges.

Worth a visit

Beautiful route on the Tour des Dents Blanches.
There is a more challenging hike on the site that allows you to make a circular loop in this sector of the Dents d'Oddaz.

Always be cautious and plan ahead when you're outdoors. Visorando and the author of this route cannot be held responsible for any accidents occurring on this route.

the climb from Les Allamands is motivating and enjoyable, but it's disappointing that the lake is dry.
the return trip to the Golése refuge is nice, but after the refuge, the trail is boring.

We went on a beautiful hike, setting off at 7:30 a.m. to avoid the heat of the day on the climb.
Once we reached the end of the marked trail, we decided to continue on to the Bostan Pass. The climb is quite steep but not particularly difficult, and the view at the top is simply magnificent. Don't miss it!
As for Lac des Verdets, it is completely dry. All that remains are rocks.
The return route to the car park is rather long and not very interesting from the Angolon refuge.
Overall, it's a very beautiful hike of nearly 18 km and 1,263 m of elevation gain, including this little detour to the pass.

A superb hike with no technical difficulties but quite physically demanding with an elevation gain of nearly 1,000 metres.
Once you pass through Bostan Forest, the panoramic views from the mountain pastures are magnificent.

Very good road conditions along almost the entire length of the hike, except for the section between the two refuges at Bostan and La Golèse. No worries, even in the rain...! In our opinion, the hike is 'easy', even with children. It took us less time than expected (about 4 hours).

A pleasant hike. The climb is easy and presents no difficulties.
Very pretty scenery.
For the more adventurous, completing this hike via the Col de Bostan is a good idea. For us, it turned into a blueberry picking trip.

A very pleasant route, offering good value for money in terms of accessibility, views and physical effort (challenging but not exhausting).

The first quarter (approximate proportion) of the hike is uphill through the Bostan forest. You come out onto the Bostan mountain pasture, with lovely views of the Dents d'Oddaz, and finally arrive at Lac des Verdets, clearly visible on 06.06.2022. At Lac des Verdets, there are lovely views of the mountain pasture you have just crossed, the lower part of the Giffre valley and the mountain ranges beyond. The return via the Col de la Golèse offers lovely views of the Pointe de la Golèse massif before descending back into the woods.

I extended my hike by climbing (there and back) from Lac des Verdets to Col de Bostan, located just over 2km away (elevation gain +350m). The view from the pass is well worth the effort: you gain height above Lac des Verdets and are rewarded with a beautiful panorama of the Swiss side (the pass is on the border). The trail itself is relatively accessible, but physically demanding in places. Be careful of patches of snow, which are still present in large numbers on the slope leading to the pass, even after a rather warm May.

The route is accessible, but be sure to bring water and good footwear. Hiking poles are also recommended (especially if you climb up to the Col de Bostan).

A route with no difficulty
Climb in the cool of the woods.
Not a single drop of water left in the lake, but the scenery is magnificent as usual.
We had a good blueberry harvest.
Please note that the car park is called Plan des Arches; this is indicated on all road signs (Les Allamands is the hamlet just below).
