Park in the abbey car park.
(S/E) Head straight on towards the Dôme les Fays: yellow and green markings. About a hundred metres further on, veer slightly to the left to stay as close as possible to the Ruisseau de Valcroissant, then cross it via the footbridge. Then let a path on the right branch off and reach a new junction just after crossing the stream again.
(1) Go straight on, ignoring the markings, and rejoin them further up.
(2) Cross the marked path to reach the opposite side and head for the Fontaine de Juillet, where you will find the yellow and green markings again.
(3) Continue to the right. The south-facing path turns left further on and begins a series of switchbacks on the steepening slope. You will reach a junction situated just at the entrance to the Vercors High Plateaus Reserve, classified as a Sensitive Site.
(4) Keep left, leaving the markings behind, and follow a small path visible through the grass to the junction with the GR®91.
(5) Turn right and continue for about 200 m.
(6) Turn right towards the Dôme and climb straight up to the summit.
(7) Enjoy the 360° view, then retrace your steps down the ascent route to Valcroissant Abbey (S/E).
