Pic de Bastan
* From Col de Portet (2215m), follow the well marked GR10 crossing first some wide pastures, then going to the Bastan lakes, in the order : Lac de bastan Inférieur, then Medium (the main and largest one), then Supérieur. Climb then via the granite boulders, but on still well visible path, to Bastan Pass. The Bastan lakes are a fairy like place and you may spend few hours wandering around the complicated shapes of the shores. On a promontory of the lake is located one of the most beautiful huts of the area, the Refuge de Bastan, which also has the particularity to be one of the few not to be owned by the french CAF, but another organism , the ASPTT of Toulouse (contact them for reservation on 33 561 148 600)
* From the Tourmalet, walk up the valley of Campana du Cloutou with its multiple lakes too: Réservoir des Laquets, Lac de Gréziolles, Lac du Campana du Cloutou, Lac d'Arrédoun, Lac de la Hourquette, just below the Bastanet Pass. On the Lac du Campana is located another mountain hut, the Refuge du Campana du Cloutou ( 33 616 663 037, owner : CAF de Bagnères)
* From the Lac de l'Oule, one can either join the south itinerary via the Bastanet lakes, or the north one via the Hourquette pass, another sharp pass as high as the Bastanet Pass and just next to it.
