Park in the Goules car park, located on the D941 after the village of La Fontaine du Berger (when coming from Orcines).
(S/E) From the car park, take the path through the undergrowth to the intersection with a beautiful track.
(1) Turn right onto this beautiful forest path through the undergrowth, which has a slight upward slope. Continue to a new intersection where signs indicate the direction of Sarcoui and Puy des Goules.
(2) Turn right towards Sarcoui. Reach the Grand Sarcoui cave. Then turn left onto a path that climbs to the top of the volcano.
(3) Turn around, descend back to the cave, then turn right to return to the intersection you took earlier.
(2) Turn right and follow the path for about 200 metres.
(4) Then turn left towards Puy des Goules. Reach the rim of this splendid, perfectly regular Strombolian crater.
(5) Walk around the crater (beautiful 360° panorama). N.B. It is possible to descend to the bottom of the crater.
(5) Descend (north-northeast).
(4) At the bottom, continue along the path on the left and keep going straight ahead, ignoring the two paths that branch off to the left and right. Continue downhill until you reach a crossroads. Then turn right and continue around the Grand Sarcoui. Ignore the path that branches off to the right and keep going straight ahead. You will reach another crossroads at an altitude of 963 metres.
(6) Turn right and continue without leaving the path (east) until you reach the D559.
(7) Follow the road to the right. At the 916-metre mark.
(8) Turn off onto the wide path on the right for a few metres, then take the path on the right again. Walk alongside a beautiful meadow on the left and a pine forest on the right until you reach an intersection.
(9) Continue left to point 964. Continue straight ahead, ignoring the other paths that branch off to the left and right. You will come to a forest road. Follow it for a few metres until you reach a small path that branches off to the right before the departmental road. Take this path on the right to return to the car park (S/E).
Moderator's note added on 13/09/2021: access to the Sarcoui caves is difficult and the summit is now off-limits (see comments).
