You can easily reach the foot of the waterfall in just over half an hour from Autoire (follow the signs). From here the path begins in serpentines up the rocks - difficult, but worth it because of the great view!
There's a beautiful signposted circular trail around Espédaillac (approx. 1 hour). Panels explain notable houses, fountains, etc., providing a good understanding of this town on the Causse de Gramat.
