An introduction to the pastoral and historical aspects of the region. Visit the Luz valley to get your bearings : 10th-century Château Ste-Marie at Esterre, old paths to the small villages of Vizos and Saligos, churches of Sère and Esquièze, Old houses and bits of history in our notes give insights into what you are walking past. Four options here, from 2h to full day walk, 5 km & +/- 300 m to 15 km & +/-1000 m. Perfect for a warm up or a half rest day, or a big climb high above the valley.

Walk from Luz to Barèges (or vice versa) on the GR10 (the long-distance hiking trail that crosses the French Pyrenees from the Atlantic to the Mediterranean), passing through historic villages along the banks of the River Bastan. The view from the cross at St-Justin is sensational, as are the crêpes at the crêperie! For the more energetic, there's an additional loop via the Montagne Fleurie. 9.5 km, +920m, -210m for standard option, +10 km and +/- 700 m for extra loop.

The Barrada valley rises behind the largest hydroelectric power station in the Pyrenees. At the head of the valley is the charming Cirque de Lys, a hidden gem off the beaten track. 10.5 km, +/- 700m. The Croix de Sia with a return via Sazos is a great alternative if you're outside the Gavarnie bus season or would like a shorter walk. 11 km, 490+/-m.
