Park at the Col des Montets car park, but it is often full of coaches.
If this is the case, park 300 m further down at the free Lac Blanc car park, downstream from the Col des Montets.
(S/E) Cross the road, then turn left at the next junction onto the path leading uphill. You will reach the junction by the chalet at the Aiguilles Rouges Nature Reserve. Here, join the Mont-BlancGRP®® trail.
(1) Turn left onto it and follow the red and yellow markings on the path coming from the Col des Montets. Pass through a very steep gully, which is well-maintained with plenty of steps. You’ll reach a small plateau.
(2) Continue along theGRP®® on an easier section of the path until you reach a crossroads with a signpost.
(3) Leave theGRP®® here and turn right to reach the Lacs des Chésérys. Walk alongside them, then rejoin the GRP®® a few hundred metres further on.
(4) Join it again on the right and continue the ascent to reach Lac Blanc and its mountain hut.
(5) Turn back to begin the descent via the same route and return to the previous junction.
(4) Here you have two options:
- turn left onto the lakes trail,
- keep to the right on theGRP®®,
in both cases, you’ll return to the junction with the signpost.
(3) From here, follow the route back in the opposite direction to return to the Col des Montets car park (S/E).
