Head to the small pass of Tamié (signpost), take the Route de la Ramaz (signpost), continue along the Route de la Belle Étoile, pass two hairpin bends and stop at the hiking sign; there are parking spaces along the track.
(S/E) Set off along the track and take the path on the left at the hairpin bend. Follow the path, which is easy at first, and ignore the path branching off to the right. The climb, with its hairpin bends, is steady. You will reach a crossroads.
(1) Ignore the path leading down to the right, continue and cross the newly created track (not shown on maps, track created in thefirst quarter of 2021). When you reach a junction at the start of the summit ridge (signpost), follow the ascending path to reach the Croix de Perillet.
(2) From there, the path follows the summit ridge; ignore the path leading down to the left, continue on, with a few sections requiring the use of your hands, and reach the summit of La Belle Étoile.
(3) Enjoy the 360° view.
Caution: a tricky exposed section, equipped with a handrail and ladder from here.
Continue along the path that follows the ridge to reach the Pas de l'Âne.
(4) A tricky section with a cable and rungs; continue, pass under the two EDF pylons and reach the crossroads.
(5) Continue and pass the Col de l'Alpettaz (signpost), then the clearly visible Chalet de l'Alpettaz. Follow the ascending path and, further on, continue to the right up a steep climb to reach the cross at the summit of Roc Rouge or La Négresse.
(6) After a long pause to take in the view, turn back and return to the junction below the Col de l'Apettaz.
Head right, towards La Ramaz / Les Combes, along the narrow, slightly ascending path. Very soon, descend into the shaded forest (yellow markings), pass through several gullies and reach a crossroads.
(7) Ignore the descending path, follow the trail, which climbs very slightly at the start, and continue until you reach the area below the Chalet de Périllet.
(8) Follow the descending path (yellow markings), cross the new track several times, follow it for short stretches, and reach the start of a path on the right, below the track and near the 1186m mark.
(9) Head off along this path, marked in yellow. The path, which is very pleasant and fairly wide, leads directly back to the starting point (S/E).
