Access: once past the Chambon Dam, turn left towards Mizoën then Besse. In Besse, drive through the village and continue to the hamlet known as Le Gay. Opposite the campsite, take the track to Col Saint-Georges. Please note: this route should be avoided by vehicles with low ground clearance, as they may struggle on the bends.
(S/E) From the Col Saint-Georges car park, turn left towards the ruins of the Chalet Josserand, then continue right along the road.
(1) At the first junction, leave the track leading to the Refuge du Rif Tort on your left and continue down the track on the right. The road ends and gives way to a footpath that follows the Rif Tort and leaves it just before you reach its source.
(2) From this point, the route heads off the beaten track along the ridge overlooking the Vallon de la Buffe; you can soon make out the Chalet de la Grande Buffe below. This ridge marks the border with the Hautes-Alpes. Continue along the ridge, passing close to the source of the Rif Tort. The summit of the Gros Têt is easily reached.
(3) From there, head south down towards the Vallée de la Romanche until you reach the Petit Têt.
(4) Complete the ridge walk by heading towards the Plateau d’Emparis, whose lakes are already visible.
(5) Cross theGR®50-54path without following it and continue straight on towards the plateau to reach the first lake, Lac Lérié.
(6) Continue along the first lake towards the second, Lac Noir.
(7) After going round the plateau and skirting Lac Noir, head back towards the Col Saint-Georges car park, heading north-west.
(8) At the junction, you can turn left to see the first of the Cristalilns Lakes. The return route, however, heads off to the right and continues down the plateau. Once you’ve passed the rock-filled section, the path joins theGR®50-54at the fords.
(9) Follow the GR® trails to the left to reach the car park directly (S/E).
