The Vercors massif has a few watering places. One of them is located on this trail, under the crossroad between the GR91 and the "Col de l'Arc" trail. The water is fresh.
The "Refuge des Allières" offers a pleasant stop, especially when the weather is hot, but it is also open most of the year and welcomes tourists and hikers in a splendid house typical of Vercors.
Please note that the cliffs on the "Vallée de la Gresse" side, namely the East side, are very abrupt, with a steep precipice. If you hike with your children, keep an eye on them and prevent them from venturing close to the cliff's edge. This is also true at the summit of the "Pic Saint Michel".

Starting point in Saint-Andéol (Isère) - 38 - Isère A vertiginous and rarely-taken loop, where you come across ibexes and chamois at every hairpin bend. Make sure you always have a helmet (ibexes love to send stones flying), as well as crampons and an ice axe until late in the season, as névés remain in place fairly long within the steep Serre-Brion couloir. It is best to start your hike early in the morning so that snow is still hard when reaching this couloir.
