Access to the start: from Brezons, follow the D39 towards Albepierre and Murat. At the hamlet of Bourguet, where the D39 turns sharply to the right, continue left at the bottom of the valley towards Dolvadenche and Sanissage. Car park at the entrance to Sanissage.
(S/E) From the car park, take the wide, obvious path along a low wall, parallel to the bottom of the valley (double markings: blue and yellow). This will take you to the Saut de la Truite waterfall (footbridge).
(1) Go back a little and follow the path that climbs diagonally to the right (north-west). In the undergrowth, pass a gate marked with a blue chevron on your right to reach a wide track higher up. Follow this to the right (north) to reach the Livernade waterfall (viewing platform).
(2) Continue climbing in a north-westerly direction. This will take you to the Cascade de l'Arbre de la Biche waterfall (footbridge over the stream).
You can return to the car park (blue markings).
(3) Continue climbing on the right bank (west) of the stream, following the sparse yellow markings, until you reach the mountain pastures. About a hundred metres after leaving the undergrowth, at a stake, turn right towards the Grandval waterfall.
(4) Follow the path downhill along the stream, on the right bank, heading south. After 150 metres, cross to the left bank and descend into the undergrowth, following the yellow markings. Join the blue markings near the Arbre de la Biche footbridge, turn left and continue downhill on a wide path.
(5) Alternative: return trip to the Traou de Lougue waterfall (not tested: signposted 15 mins return trip).
Continue downhill (south)
(6) Turn right onto the tarmac road and you will soon reach the starting point (S/E).
