From Chevenoz, drive up to Prebuza and park at the end of the tarmac road (car park near a water reservoir).
(S/E) Take the path that climbs through the woods towards Le Petit Chesnay (GR® red and white markings). Stay on the marked path which climbs steeply through the woods and ignore the side paths. Leave the woods, go through a gate and arrive at the barns of Sur Les Trables.
(1) Continue due east along the track through the mountain pasture. Carry on through the woods towards Le Petit Chesnay (GR® markings).
(2) At Le Petit Chesnay, follow the signposted path which descends slightly to the left. Continue eastwards along this path to Le Grand Chesnay (drinking water, beautiful views over the Pays Gavot, Lake Geneva and Switzerland).
(3) Continue eastwards across the mountain pasture. Beautiful view of the Dent d’Oche and the Roc du Château d’Oche.
(4) At the Croix du Grand Chesnay, turn right towards the Col des Bœufs. After a short descent (ignore a path branching off to the left) followed by a climb towards the spruce trees, you reach the foot of Mont Baron, from where you can see the other side (the Abondance valley) with a glimpse of Mont Blanc.
(5) Descend towards the Col des Bœufs (leave the path on your left that climbs between the rocks towards Mont Baron).
(6) At the Col des Bœufs, leave theGR® and turn right (south-west) towards Les Grandes Heures and Vacheresse. Shortly afterwards, join a track and follow it south-west (ignore the path on the left towards Les Grandes Heures). Pass the Chalets des Bœufs and descend in hairpin bends onto the main track.
(7) At a hairpin bend to the left, ignore the turn-off to the right towards La Croix / Le Fontany and continue along the main track towards Taverole. You will almost immediately reach a fountain between two chalets. In front of the last of these chalets, leave the main track and follow a path to the right which descends into the woods towards Taverole behind the chalet.
(8) At the junction, pass a first uphill path on your right, then shortly afterwards a second. Continue downhill to the Ruisseau de Taverolle.
(9) Then turn left and follow the stream downhill. The path turns into a tarmac road leading down towards the hamlet. At the first hairpin bend to the left, leave the road and take the path leading off to the right towards Prébuza (signposted 45 mins). Follow this shaded path as it climbs gently and, after a solitary chalet, you’ll reach a junction.
(10) Take a steep path on the right. At the end of the short climb, at a T-junction, turn left. Follow the path which passes near scree (quarry) and leads to the hamlet of La Croix. From here, stay on the tarmac until the finish. Continue along this road (with little traffic) to a crossroads.
(11) Head up the road from Chez Pollien, passing beneath an imposing building – a typical farm of the Abondance valley – and close to an old bread oven (information boards). Leave Chez Pollien, pass in front of a former holiday camp and arrive at La Billette (cross).
(12) Continue straight on (west) for about a hundred metres. Take thefirst road on the right which climbs up towards Prébuza. At the junction, go straight on, pass the reservoir and you will immediately reach the car park (S/E).
