Access: from Praz de Lys (74). Walk through this resort (towards Col de la Ramaz) and, almost at the exit, park at the Moliettes car park (Les Bétex), opposite the Jean de la Pipe restaurant.
(S/E) From the car park, cross the ski run arrival area and take the road leading up towards the Col de la Ramaz for about a hundred metres, then head up to the left along the fairly steep slope (with a few scattered spruce trees) to a small pass at the start of the Lac de Roy plateau. ''Throughout this initial climb, there are superb views of the Pointe d’Uble, the Roc d’Enfer, the Pointe de Chalune and the Pointe de Chavasse.
Lac de Roy, a splendid mountain lake in the heart of the mountain pastures, offers a refreshing break!”
(1) Continue to the left of the lake and join the path that climbs steadily up the mountainside through the mountain pastures until it joins a wide path.
(2) Ignore the first path on the left (to be taken on the way back), and a second one shortly afterwards, and head for the Pointe de Perret.
(3) Continue to the right along the wide path towards the Pointe du Haut Fleury, at an altitude of 1,981 metres.
(4) At the summit, two orientation tables offering a 360° panorama help you get your bearings. From mid-July to mid-August, the summit can be reached by chairlift. The view stretches from the Jura Mountains and Lake Geneva to the Chablais Massif, Mont Blanc and the Aravis.
Descend via the same wide path back to the Pointe de Perret.
(3) From Pointe de Perret, head back down the same path you took on the way up for a few metres until you reach the junction with thesecond path on the right.
(2) Follow this path downwards; it leads to Lac de Roy, skirting it on the right.
(5) At the junction, carry on straight ahead to the Chalet du Roy.
(6) From the chalet, retrace your steps towards Lac de Roy.
(5) At the junction, take the path on the right which runs alongside the lake. Cross the small stream, which has been lined with stones, and head to the far end of Lac de Roy, at a junction you passed on the way there.
(1) Head back down via the same route you took on the way up to return to the car park (S/E).
