The Flaming Fountain circuit

Park in the car park of Saint Barthélémy du Gua, at a crossroads of Route du Col de l’Arzelier.

Go onto the road opposite 200 m on Route du Col de Arzelier. Leave it to take the wide track on the left (1) leading to the village of Pierre. At the village entrance, turn left and head slightly downhill to reach the D8.
Stay on this road and turning right, take the path down to the Flaming Fountain (2).
Back at the turn, follow the road to the village of Miribel Lanchâtre.
Leave the D8 by the left (sign: A physically demanding route), then left again 100 m further on (3). This trail with Vercors-style green and yellow markings, remains level before starting on a good downhill stretch to the hamlet of Garin Essart (4).
Do not cross the bridge over the Gresse. Stay on the left bank then undertake the ascent to Saint Barthélémy on a green and yellow marked trail that starts on the left at the bridge.
Ignore a path on the left and at the next intersection, turn left, then immediately right.
Reach the D8 at the entrance to the village and turn right to reach the starting point at the car park (5).

No water, no shelter on this route.
The Flaming Fountain is a feature of this area. The gas coming out in places above the water course are flammable, which gives this place its magic.
A space has been set up along the water, with the welcoming name Verdant de Cassoulet, and in the middle of the space, the flame burns continuously.
