Park in Tioulévé, also known as Lieulever.
(S) Go back down the road for 80 metres and take the path on the right.
(1). At the start, the path also serves as a discovery trail. After the place called Le Mouilles, the path turns sharply to the right.
(2) At a hairpin bend, leave the discovery trail and continue to the left. The path heads west, passes under a high-voltage line and begins a short descent towards an isolated chalet.
(3) Before reaching the chalet, the trail enters the forest for a sustained climb.
Along the way, the trail is joined on the left by another trail coming from Barbet. Continue climbing to emerge in the mountain pasture at a place called Le Chenalet (signposted, altitude 1,700 m).
(4) Continue north for 100 m and at the next intersection.
(5) Turn sharply right and climb up to Pas des Chèvres.
(6) Take the left option, Lac Noir via Char de la Turche, which you will reach after a difficult climb.
(7) At Char de la Turche (2,010 m), follow the clearly visible path heading north. It begins with a descent that must be approached with caution, then climbs again, avoiding the ridge path, and ends up slightly above Lac Noir.
(8) Pass the lake to the south, cross the torrent, which serves as an outlet, then after a series of descents and ascents, the trail begins a long descent. The slope becomes gentler as you enter the forest.
(9) Leave the path leading down to Les Plattières on your left, then cross the stream on a metal footbridge.
(10), rejoin a section of the Sentier de Découverte and the hamlet of Tioulévé (E).
