Road access: from Seix, head towards Guzet (D3) and at the hamlet of Pont de la Taule, turn off towards Couflens / Salau, passing through Couflens and then Salau. Pass the first car park and continue along the road to park near the old mine buildings (end of the road).
(S/E) Walk towards the buildings; the path starts between two buildings on the right, and the climb begins. Follow this well-marked path. You will notice the remains of the mines on the right.
(1) Shortly after crossing the small stream, the path climbs to the left, winding through the forest to emerge at the entrance to the cirque.
(2) On your right, you can see where the stream disappears (square metal grating; be careful, there are many holes in the grass).
The path continues at the back of the cirque, passing to the left of the cirque and disappearing into the stream for a while. Continue to the waterfall.
(3) Return via the same route to the car park (S/E).
Definitely worth doing again.
