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 to the right and then climb up to the Col des Espécières. From the pass, the panorama is completed by a sweeping view over 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 to a trail junction marked by a cairn.
(2) Leave the ridge path. Turn right towards the north-east onto the Pic de Saint-André path. The path descends a few metres before climbing up the slope and becoming less distinct.
Continue climbing 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 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!)
