The start of this route is at Les Signaraux above the small village of La Motte d'Aveillans (about 35 km from Grenoble towards La Mure on the D529). Les Signaraux is a small family ski resort with two or three ski lifts and cross-country ski trails that wind through the mountain pastures. The route starts from the car park located at the ski lifts, so do not stop in the hamlet, as the hike will be a little longer from there.
(S/E) From the car park, join a wide path below the ski lifts (signposted). This path is almost flat at the start, even descending slightly, then after about half an hour on this alpine path, which climbs gently southwards, you will arrive at the foot of the Col du Sénépy.
(1) Turn left, the slope becomes much steeper and you first climb up a path, then through the mountain pasture to the Col du Sénépy (1,526 m), where there is a refreshment stand for cows.
(2) To reach the summit of Sénépy, a very wide track winds its way southwards. It is not advisable to take the shortcuts that seem obvious, as they contribute to the degradation of the mountain pasture by accentuating erosion due to the fairly steep slope.
(3) Once at the summit, enjoy the 360° view of the entire region, including Trièves, Oisans, Taillefer, Belledonne, Chartreuse and the entire Vercors mountain range as far as Mont Aiguille. You can also see the magnificent Monteynard dam lake on the Drac river.
To return, descend to the Col de Sénépy.
(2) Take the path through the mountain pastures that more or less follows the summit ridge towards the east. Pass the summit of Serre de l'Horizon and continue along Serre de la Combette. The path turns north until it reaches a fork.
(4) Keep right, heading northeast, and reach the summit of Pierre Plantée (1,559 m).
(5) Enjoy the view, then return to the previous fork.
(4) Continue right downhill towards the north-west, cutting across a bend in the track and then rejoining it below (elevation 1,421 m). Turn left and rejoin the path taken on the way up. Continue downhill and return to the ski lift car park (S/E).
