To reach the starting point: in Virieu-le-Grand, follow signs for Thézillieu, then Cascade de Clairefontaine. After a bridge, turn right towards the waterfall. Continue to the end of the tarmac road and park (at the starting point) after the final left-hand bend.
(S/E) Retrace your steps for about ten metres and take the path branching off to the left. Follow this path, keeping to the left before a private property. Pass a house on your right where the path then narrows sharply.
Take the second track on the right, as the first is a dead end, and head up into the forest where numerous tracks cross. Take the widest one and arrive at a junction where the view opens up.
(1) Take the track leading off to the left, heading back into the forest.
(2) At the next junction, do the same as before: turn left. You’ll come to a short climb heading off to the right; take it. Once at the top, the path heads left and runs along a ledge for a while amidst box trees that were attacked by the box tree moth in 2019. Some are starting to recover slowly. You’ll come out onto a wide track suitable for jeeps.
(3) Head up to the left and stay on this track until the next fork.
(4) Take the left-hand path that climbs.
(5) Look for orange markings on your left. Leave the track and climb one or two metres, avoiding going straight ahead. Immediately turn right onto a barely visible path. An arrow helps you take the right direction.
The path becomes clearly visible after a few metres and leads onto a wide track. Follow it for a while until you reach a junction.
(6) Turn left to avoid heading towards Masot. Pass Cul de Masot and follow the path through the forest, which becomes less distinct at times, especially in autumn when the leaves fall. You’ll come out onto a good path; continue straight ahead until you reach a large crossroads.
(7) Turn left onto the path that climbs slightly.
(8) At this junction, take the path on the right . Generally speaking in this section, if in doubt, always take the path that climbs the most. You’ll come out onto a wide forest track and turn left towards the Belvédère de Sérémond, arriving at a large, often muddy clearing used for timber hauling.
(9) Continue to the left to cross this area, with the “Cabane de Robert et Fifine” on your left. Then take the widest path, slightly to the right.
(10) Look for a path branching off to the left and take it. At the junction of two paths, turn right and arrive at a large clearing. Look for the track on the left leading to the viewpoint. The markings and signs are oriented for those coming from the opposite direction!
(11) Retrace your steps and continue the walk by heading left.
(12) Shortly after a gate and a signpost, before the path starts to climb, take the track on the left which leads in two wide bends onto the D53. Turn left onto the road and follow it for about 500m. This is the tarmac section of the walk ; proceed with caution.
Just before a bridge, take a small, steep, clearly visible track on the left. After a few metres, take a track on the right and follow the path, which is muddy in wet weather and sometimes disappears into the grass. Never cross the stream. You will come out onto a track suitable for vehicles.
(13) Turn right towards the Clairefontaine Waterfall and follow the yellow markings leading to the waterfall. Continue down the path, which leads to the tarmac road taken on arrival. Turn left onto it and return to the starting point (S/E).
