A looping 45km circuit in the vertiginous Vézère gorge, best obeserved from the site de la Roche. Beyond Allassac on the D 9, a pleasant little road leads to the edge of a precipice dropping into the gorge. On the right, a track leads through the chestnut trees to an orientation table (391m); the view stretches from the wooded Saillant gorge nearby to the village of St-Robert. On the left, the panorama shows the gorge in its full glory.
