Access by car
Park in the car park near the Bétex ski lift, on the side of the D308 and opposite ‘Chez Jean de la Pipe’.
(S/E) Carefully follow the road up to the Col de la Ramaz (D308) for about a hundred metres. Shortly after passing the Roy chairlift, head up to the left along a wide, clearly visible track.
(1) At the water intake building, turn left. The track quickly narrows to become a path, then crosses a small stream. When you reach a track, continue left to reach the charming Lac de Roy.
(2) Two paths are visible on the right. Ignore the path furthest to the left of the two, which goes round the lake. Continue along the path furthest to the right, which is sometimes hard to see but heads towards a clearly identifiable isolated rock. Go round the rock on the right and continue the climb.
(3) Where the track from the left joins (visible only at high zoom), continue straight ahead on the track until you reach a three-way junction.
(4) Keep to the right and continue to the hairpin bend. At the bend, climb left for a few metres up a short steep slope to reach a path junction.
(5) Turn right towards Pointe de Perret. The climb offers magnificent views of Cluses, the Bargy range and the Aravis range.
(6) Turn left onto the path that follows the ridge line, then joins a track coming from Pertuiset. The view from the summit and on the descent takes in the Bargy, the Aravis, the Arve Valley, the Genevois region, and the resort of Sommand, dominated by the Haute Pointe.
(7) Take a sharp left-hand bend to traverse the hillside. Just before reaching the pass, the path splits into two tracks, either of which can be taken: the route follows the track on the right. Once on the ridge, take the path on the left.
(5) Continue straight along the path taken on the ascent for 150 m.
(4) Take the path on the right. This becomes a track which you follow to the Chalet de Roy.
(8) Pass the chalets and continue along the track. This soon reaches a small pass, then begins the descent to the left towards Praz-de-Lys. Follow it to the junction with a road.
(9) Turn left to follow this road, which climbs gently and leads to the car park (S/E).
