Start from a car park located almost under the A8 motorway (exit 38) after 4 km on a small road, signposted "site de Malpasset".
(S/E) From the car park, take the small road along the Reyran valley. At the first fork, turn right and follow this road (signposted). Along this section, you can still see the huge boulders that were carried away, reminders of the disaster.
(1) Return by the same route, which is about 2.7 km there and back
Back at the car park, go under the motorway and take a track below.
(2) Cross a ford and continue along theGR®57trail on the right, which climbs up the Vallon de l'Apié d'Amic until you reach a fork.
(3) At this fork, turn right and then a little further on, turn left, staying on the wide track... the climb is steep. A little higher up, at the cistern, turn left again.
(4) Continue along this track, known as the Esquine (meaning "the back" in local dialect), until you reach elevation 306.
(5) At the hand-written sign, a small, fairly steep path leads to the car park.
(6) Pass the picnic area at the beautiful little Lac de l'Avellan. Walk along the lake for about 100 metres.
(7) In this open space, look for a small dirt path on your left, at eye level. Be careful not to miss it, as it is the one that descends along the steep-sided Avellan valley
(8) At elevation 79, turn onto the wide track on the left, then continue on flat ground. Follow it to elevation 68 to rejoin the path you took on the way there.
(3) Retrace your steps to return to the car park (S/E).
