Description

This educational loop leads from the puy de Combegrasse, a strombolian volcano, to the puy de l'Enfer, whose pozzolan quarry enables us to study the heart of a volcano, and to the narse d'Espinasse, a peat bog in an explosion crater.

Guidebook with maps/step-by-step

1/ From the start sign, take the stony path near the disabled parking area, ignoring the adjacent paths. As you go downhill, turn left onto the pozzolana path before the picnic area, and continue along the path which enters the pastures through gates and sluices and reaches the summit of the puy de Combegrasse (panoramic view, orientation table no.1). Continue along the ridge path to orientation table 2 (panoramic view). Make a U-turn for 150 m to the low point.

2/ Turn right and follow the downhill path marked by a small fence. At the end of the sluice, keep left, cross the pine wood and continue right along the grassy path. Go through the gate, back to the picnic area and return to the path at the start of the circuit. Turn left and then right at the road. Continue straight ahead until you reach another road.

3/ Go right for 20 m, then cross the road and take the first track on the left near a farm building. At the crossroads, turn right and then right up the track. At the edge of the Puy de l'Enfer wood, keep left to follow the grassy path down to the narse (with a bird's-eye view of the narse). At the bottom of the descent, turn left, then immediately right twice in succession. At the junction of four paths, take the one on the right and climb up to a road.

4/ Turn right, cross Espinasse, keep right to pass a small cross and, at the fork, turn left to reach a road. Cross the road, continue straight ahead for 250 m and, at the crossroads, fork right. Follow this track, ignoring the adjacent paths (view of the Chaîne des Puys, Puy de Combegrasse), and continue straight ahead along a grassy path. At the road, turn right for 150 m, then left onto a pozzolana track between pastures. Ignore the adjacent paths; at the crossroads at the corner of the wooded plot, turn right and follow this path through meadows and woods to the road, which you cross (beware: fast-moving traffic) to get back to the starting point.
