Nice deep pool in the Rotja river, perfect for cooling off on a long walk. Take the waymarked path from Py village (you can get a leaflet with walks from the Les Izard nature education centre in Py). This swim is at the furthest point of the walk with red waymarks, around 6 hours walk round trip from the village, through lovely deciduous forest. You might even spot a wild boar!
