Reach the hamlet of La Chambotte, either from Chindrieux or from La Biolle, via Saint-Gemain-la-Chambotte. Small car park to the west of the hamlet, just before the descent to La Chautagne.
(S/E) Take the La Chambotte road downhill, go through the tunnel then round the hairpin bend and continue to the start of a path beneath the cliff on the right.
(1) Follow this path, which climbs slightly above the road, then runs along the foot of the cliff, sometimes beneath overhangs equipped by climbers. The path then climbs to stay as close as possible to the foot of the cliff until a high point where some paint marks indicate the start of a track leading up a gully to the ridge.
(2) Stay on the path which continues level towards the north, through the forest, and emerges near the barns at Chez Carabin.
Take the small road on the right towards the Route du Sapenay.
(3) Join this road and head down a little towards Cessens to the Notre-Dame de la Salette Chapel.
(4) After a return trip to the Albanais viewpoint 50 m away, retrace your steps and take the Chez Carabin road for 50 m.
(3) Turn left onto the track leading up to the Tours de César or Château Neuf.
(5) Continue along the path past the castle, which descends into a canyon and climbs back up the opposite side to the ridge, reaching a pass at the top of a gully from which you can descend to the right or left.
(6) Climb up the opposite side to stay on the ridge path which ascends along Mont Laval, mainly on its western flank, offering occasional views of the lake where rocks emerge from the forest.
The path continues southwards to descend from Mont Laval, still mostly along the western flank of the ridge. At the bottom of the descent, it veers slightly left to cross towards the hamlet of La Chambotte, which it reaches by winding its way between the houses.
(7) Once you reach the road, turn right to reach the car park (S/E).
