In Gavarnie, take the road to Port de Boucharo and park at the Col de Tentes car park.
(S/E) At the end of the road and the Col de Tentes car park, take the signposted path (sign) to Lac des Espècières to the north-west. Follow this path to the lake, go round it on the right and then climb up to the Col des Espécières. From the pass, the panorama is complemented by a bird’s-eye view of Lac de Lapazosa and the Tendenera Massif.
(1) Turn right and, from boundary marker no. 318, follow the Espécières ridge north-west for about 300 m until you reach a crossroads marked by a cairn.
(2) Leave the ridge path. Turn right (north-east) onto the path to the Pic de Saint-André. The path descends a few metres before climbing up the hillside and becoming less distinct.
Continue climbing along this path; then, when it rises steeply and becomes very faint as you make your way from cairn to cairn, reach the ridge line.
(3) Climb north-east up the ridge of the peak to the summit.
(4) Follow the same route as on the way up back to the car park (S/E).
, but not a hike for those who are prone to vertigo! The path is not always easy to follow, so look for cairns as you approach the last pass or check your GPS position regularly (not while walking! Stop to do this!)
