The descent is rapid 3Km D-500m, a few hairpins. Good slope. Lots of stone all along, hidden under the leaves at the moment. No mud. Be careful of the water back, some are well marked. Little jump 😁 https://www.komoot.fr/tour/1376973524?ref=aso

A few steps from the village of Izeste, this pretty grassy plateau is at the foot of the Pic d'Hourcat (1,341 metres). The road leads both to the ascent of the peak and to a small bucolic path which follows the course of the Lamisou.
