Superb two-day hike. Description accurate, trails very well marked throughout.
A challenging hike but not technical. Steep climb from the refuge to Lac Blanc and from the refuge to the Col de la Mine de Fer.
Several bivouac spots at Lac Blanc. We made the round trip to the foot of the Freydane glacier in two hours without pushing ourselves.
Steep descent in one hour from the Col de la Mine de Fer to Lac de Crop, but no technical sections.
The last part from Lac de Crop to the car park is easy.
In total over 2 days: 28 km, 2,400 m elevation gain (Garmin watch).

A two-day hike with a camp-out at Lac Blanc.
Stunning scenery, technically challenging but not too much, a perfect campsite... ideal for a camping trip whilst still offering a bit of a physical challenge.
No need to carry litres and litres of water; there are plenty of springs available and none of the four of us fell ill from drinking it. Obviously, avoid taking water from the lakes; instead, collect it further upstream.
A detour via the summit of the Grand Replomb is possible for the most experienced and intrepid.
More details in the reviews I left for Days 1 and 2.

An incredible hike thanks to its stunning scenery; the steep climb in the first section offers views of Lac Blanc – and what a lake it is! A fabulous spot for camping, especially with the sunset, which is absolutely breathtaking! One slight downside to the second section: the descent after the Col de la Mine de Fer is very long and steep.
Definitely worth doing!

A challenging hike with some tricky sections. The path is barely marked, if at all, except on the GR. Watch out for snowfields.
Not a particularly scenic hike, apart from the view overlooking Lake Crop

Hi,
We did the route on Monday in foggy conditions starting at 1,600m, so we couldn’t see a thing along the ledge.
The reported total elevation gain is incorrect: 700m up to the refuge + 250m to Lac Blanc + 500m to the Col de la Mine, making 1,450m rather than over 2,000m.
On Tuesday, the fog was below the refuge and we walked above a sea of clouds. Saw chamois at the Col de la Mine and went for a swim in Lac de Crop.

A beautiful circular loop in the Belledonne Massif, where this hike starts from the mountain pastures and takes us through a mineral world to a haven of tranquillity on the edge of the Sept Laux (Seven Lakes). The return journey, along the ridge or through wild valleys, takes us around the Allevard massif.

This magnificent circular hike begins with the fairly busy route from the Muret car park to the delightful Lac de la Coche. The trail becomes wild as it follows the GR®738 across the discreet eastern slope of the Belledonne mountain range. It passes under the Pointes du Sifflet, karstic cave de la Scia and Ferrouillet peaks, offering magnificent views of the Olle Valley and the eastern face of the Grand Pic de Belledonne. In a high-mountain mineral landscape, the trail crosses the Col de la Brèche Fendue to reach the Col de la Mine de Fer. Leaving the GR®, it descends towards the superb and popular Lac de Crop, then descends its lock and crosses the forest.

This is a classic hike which, after the Pas de la Coche, enters the Belledonne Massif.
Hannibal is said to have taken this route.
There was even a road project between Grésivaudan and Le Rivier d'Allemont; the beautiful track between (6) and (7) is a remnant of this.
Today, the pass is used by shepherds, hikers, ski tourers, snowshoers and even tourist planes at an altitude higher than ours.

Agréable randonnée dans le magnifique massif de Belledonne. Le sentier commence par s'élever en direction du ravissant refuge du Habert d'Aiguebelle. Arrivé à proximité, il gravit le Pas de la Coche, passe au-dessus du mignon lac éponyme, puis traverse un champ de myrtilliers. Il passe le flanc des Roches Jaunes, rejoint le GR®738 et traverse des alpages. En longeant les falaises de la Crête des Îlettes, le col apparaît dans un décor minéral et s'atteint, après un raide pierrier, avec, comme récompense, une magnifique vue sur le Lac du Cos et les cimes du massif d'Allervard.

Loop ascending through the pretty Vénétier valley and its lakes to the Cime de la Jasse, a beautiful viewpoint due to its advanced position between Belledonne and Sept-Laux. Return via the Crête de Bedina, on the Prapoutel resort side.

This superb circular hike in the Belledonne massif starts at the Muret car park. The route leads to Lac de la Coche, then crosses the slopes of Roches Jaunes before following the Ruisseau du Clétat and climbing the Col de L'Aigleton. It descends the steep opposite slope, passes the charming little Lacs du Vénétier, then climbs to the Col de la Jasse and reaches the Cime de la Jasse via the ridge. It drops down into the Vallon de la Jasse, passes over the crest of the Montagne de Bédina, and follows a wide track to Plan Cortillets. It crosses the forest to reach Gros Caillou and then Pré de l'Arc, finally taking a gently sloping forest track to complete the loop.
