Access by car: from Lourdes, head towards Argelès-Gazost via the dual carriageway and exit at Agos-Vidalos. Park in the car park opposite the town hall, which is located along the main street, less than 1 km from the interchange.
(S/E) From the car park, head south towards Argelès-Gazost for 80 m, then take the small road (Rue des Bruyères) on the right for 50 m, which climbs towards the village.
(1) Then take the path on the left: Le Bousquet, Nageau. Continue along this hillside path for about 1,500 metres (do not take the fork on the right towards Le Nageau).
(2) After passing the church in Vidalos, cross the main road and take Chemin des Carrétères opposite to descend to the Gave de Pau river, passing under the dual carriageway. There are benches and tables where you can admire the old railway bridge (Pont de Boô-Silhen) that crosses the river.
(3) Follow the Gave de Pau river along the left bank, heading north, then pass under the dual carriageway again when you have to. Immediately after the underpass, turn right onto the small bridge and climb up to the Vidalos Tower via a fairly steep path. The tower is open to visitors (free admission) and offers a beautiful view from the top.
(4) Descend via the northern path on your right as you leave the tower, then take the small road on the right. Go under the dual carriageway again to reach the Gave de Pau river at the micro power station. Then follow the Gave de Pau northwards to an enclosure with a donkey and a goat, which will force you to get closer to the dual carriageway, which you will cross again via an underpass.
(5) After the underpass, turn right and, via Chemin du Sailhet and Avenue du Lavedan (D921b), head towards the Town Hall (S/E).
