Park in the large Odyssée Verte car park.
(S/E) Take the Sentier des Fleurs, to the right of the main track, towards the tree-top walkway park.
(1) Just before the park, continue along this path, turning right. The path descends to the resort car park. Cross the River Gresse.
(2) Take the path opposite the car park which leads to the Pas de la Ville. Very quickly, the climb becomes steep; the path winds its way up through a forest (and is therefore in the shade) before emerging into mountain pastures directly beneath the Grand Veymont.
(3) Continue straight up to the Pas de la Ville.
(4) Turn left. The path is less clearly marked as it is rockier; however, as it is well-trodden, the rocks are quite slippery and covered in moss.
Take care: some sections are a bit exposed.
Pass through a gully to reach a small plateau.
From there, if you turn round, you’ll have a magnificent view of the Vercors mountain range.
All that remains is the final section leading to the summit
(5) of the Grand Veymont (2,341 m), then begin the descent. Once on the plateau, keep to the right, heading south.
(6) Pass the Cabane des Aiguillettes (on the right) and head for the Pas de Bachassons.
(7) Turn sharply left and pass through the Ravin des Serres and du Maupas.
(8) Continue down
(9) Take a path on the left (Yellow Cross and Green Cross on a tree) at a hairpin bend to find yourself skirting a ravine. You’ll soon come across another yellow and green marker.
Shortly afterwards, there are three dry streams to cross ; you’ll need to climb up to cross them , the last one using a rope (useful but not essential).
Please note: further on, there are three more dry streams to cross. The banks of these streams have been eroded, so it is important to spot where the path continues on the opposite side. You will often need to climb up or down to cross. Ropes are provided to assist with these sections.
At each exit from the ravines, the view opens up, offering fine views of Mont Aiguille.
Reach the junction after the Barri ravine at around 1,400 m.
(10) Continue straight on, following the contour line.
Stay on this balcony-like path until you reach the Col de l’Allimas at an elevation of 1,354 metres.
(11) Carry on straight ahead, following the contour line.
(12) Carry on straight ahead, following the contour line.
(13) At the Col de l’Allimas, turn left and stay on the side of the road for about 100 metres, then head left into the forest to return to the Parc de l’Odyssée Verte car park (S/E).
