I did it on gravel, climbing via the Aveillans hill (west), it was fine. Direct descent to Putteville, very limited at the beginning on gravel, much steeper but it was fine.

1st part very smooth and very pleasant, 2nd part much more technical with a nice climb on a very greasy muddy path, steep slopes and quite technical descents. The final does not take the greenway recently set up and which allows you to avoid the road.

It is possible to do the Crête des Crocs tour by following the path at the bottom of the cliffs. You will have to pay attention to the cairn which indicates when you must leave it to reach the ridge and switch to the other side. Be careful, the path to go back down includes a technical passage that can be avoided by passing the rocky bar while staying on the ridge.

This hike offers superb panoramas and the arrival at Pic Saint-Michel, if you go clockwise, reveals a breathtaking view of the valley.

Second highest peak in the Vercors - and as usual with "second summits" 😆 harder to climb than the Grand Veymont. But, as I did on my tour, it can be crossed from both sides, T4+ to T5 (according to the SAC scale) or climbing sections 1+. I recommend going from northeast to south. More in my tour and in the second waypoint listed here, these are often marked multiple times on Komoot...
