Start from the Pont de Lajoux car park at La Chèvrerie (about 9 km from Bellevaux).
(S/E) Cross the Pont de Lajoux, then immediately afterwards follow a track on the right running alongside the riverbed.
(1) Continue straight on until you reach a path coming from La Chèvrerie (towards Lac de Vallon). At a junction, follow the path to the right, then immediately afterwards take the path on the left towards La Croix des Chartreux. You will then reach the Chapelle Saint Bruno a few metres further on (access possible on the left).
(2) Continue straight on to the Gué de la Diomaz: follow the path on the left. Further on, join another path coming from the left at a Y-junction: continue straight on along the stream bed, then shortly afterwards cross it twice at fords in quick succession.
(3) At a junction, follow the ascending path to the left: the route overlooks the surrounding area for a while before following the stream along its bed. You’ll reach the foot of the pretty Cascade de la Diomaz, where you can see the Croix des Chartreux carved into a stone.
(4) From here, you will encounter some difficulties in a rather rugged section (a chain provides assistance for the first few metres). Along the way, there are several opportunities to reach the waterfall, which is marked by a few potholes.
(5) After fording the stream bed, you reach a junction: continue left (no signposting in this direction), keeping the stream on your left at a distance. You reach another junction further on (if you miss it, you can also follow the next one).
(6) Continue to the right on a path with some steep sections. Further up, you’ll reach the final stretch of a forest track.
(7) Continue left along a path with some steep sections. You will reach a forest hut.
(8) Continue straight ahead on the forest track, then shortly afterwards, turn left onto another track.
(9) Shortly after passing a small pass (elevation 1542m), follow a path to the left which is barely visible at the start: after a long climb up some steep slopes, you’ll reach a small viewpoint on the right with views of the western sector. Continue along the ridge line, then after a junction, carry straight on along a path up steep ascending slopes. Reach the ridge line and head to the summit of Pointe des Follys, situated a few metres to the left (marked by a cross); there are some views of the eastern sector (notably of Pointe de Chalune and Roc d’Enfer).
(10) Continue the route almost due south, heading downhill.
(11) At the Col des Bétets, continue straight on uphill towards the Tête des Follys. At a junction (no signposting), head left uphill.
(12) After reaching the ridge line, you can turn left to reach the summit a few metres away (beautiful views to the west). Continue southwards along the Arête des Follys (more beautiful views to the east). You will reach a junction at the Col des Follys.
(13) Continue straight on along the path, then proceed at the foot of the imposing Chavannais cliff (area potentially exposed to rockfalls). You will reach another junction at the Col des Charmettes.
(14) Turn left and follow the path, which joins a ridge line further up (be careful, as you are passing very close to very steep grassy slopes which themselves overlook cliffs not far away).
(15) You reach the Col des Chavannais: follow a path on the left to reach the summit of the Pointe de Chavannais, which is not far away (take care as the route runs directly above cliffs).
(16) Turn back to the Col des Chavannais.
(15) Continue the route to the left, on the other side of the valley (towards Chalet de Chalan): fairly soon, take another, less marked path to the left and continue downhill through rather stony terrain with some steep slopes. Further down, there is a short climb before you reach a mountain pasture: go straight on at the junction (at a place called Chavan) and continue downhill.
(17) Just before the Chalet de Chavan (mountain hut), continue to the right towards the Pâturage de Pététoz: head towards the Pointe de Chavasse, which you then follow along its base over a few steep ascents in rocky terrain (caution: this entire area is potentially exposed to rockfalls).
(18) You will reach two steep sections in succession (thefirst is equipped with chains) requiring a degree of caution, then climb up a wide grassy valley.
(19) Continue straight on until you reach a Y-junction (at a place called Pâturage de Pététoz): the route takes you through alpine pastures at the foot of the Pointe de Chalune and joins the Col de Jorat, before reaching the Chalet de Pététoz.
(20) Near thefirst chalet, head left towards the Pont de Lajoux: the route passes close to a second chalet, then shortly afterwards follows a track entering the forest for a descent. Join another track coming from the right.
(21) Continue left along a path where you will encounter a difficult section on a steep, steeply sloping section. Further down, you will come to another path: continue straight ahead.
(22) At the end of the path, follow the track to the left. A little further on, turn right at a place called Lajoux to return to the car park (S/E).
