To reach the small Clot car park, leave the departmental road just before the entrance to the village of Saint-Christophe, take a small road on the right in a hairpin bend towards "Le Clot" (signposted) and continue to the hamlet.
(S/E) From the car park, continue along the path, cross the hamlet and take the first path on the right. This will take you to the Vénéon torrent, which you can cross.
(1) At this intersection, take the path that branches off to the right towards the north. After about 200 metres, the path crosses the Mariande torrent and you can see the Mariande waterfall.
(2) After crossing this stream, take the path on the left, which begins a steep climb.
(3) Take the path on the right that heads north again.
Note that it is possible to continue climbing in the same direction and turn right a little higher up at an altitude of 1,850 metres. The two paths then join together to cross a kind of plateau, then descend slightly towards the small Refuge de l'Alpe du Pin.
(4) Once you have passed the refuge (usually open from the beginning of June), continue on the same path, which begins to descend.
(5) Take a break to admire the magnificent Froide Pisse waterfall, which is very well fed by the melting snow. Continue downhill to the next intersection.
(6) You will reach the trail that winds above the Vénéon. Turn right towards the south and continue on the same trail.
(2) Return to the ascent route and continue.
(1) Turn left, descend to the stream, cross it and turn left uphill to return to the starting point (S/E).
