Day
1

Cauterets - Refuge d'Ilhéou

Duration: 03:25 h
Distance: 7.82 km
Ascent: 1040 m

The journey begins gently from the lively streets of Cauterets and quickly slips into a greener, quieter world. Forest paths, flowing water and a steady sense of ascent mark the beginning. It feels approachable, but the mountains make it clear you are leaving the valley behind.

The trail follows the Gave de Cambasque, passing the Gave de Cambasque waterfall and higher viewpoints over the Ilhéou waterfalls. As the path climbs, trees thin out and open slopes appear. Near Black Lake, the scenery turns more alpine, with wider views and a feeling of space.

The refuge lies beside the calm waters of Lac d’Ilhéou, surrounded by high ground. It is a beautiful first mountain stop, where the day ends quietly with reflections on the lake and the peaks above.

Refuge d'Ilhéou - Refuge Wallon-Marcadau

Duration: 04:10 h
Distance: 10.1 km
Ascent: 600 m
Descent: 750 m

This is a varied and rewarding mountain day, with a real sense of movement through changing landscapes. From the first steps, the terrain feels more open and the views stretch further with every climb.

A steady ascent leads to the Col de Haugade Supérieur, where the world suddenly opens up. The path then weaves past the Embarrat Lakes, Lac du Pourtet and Lake Nère, each with its own colour and mood. Ancient pine trees mark the transition back into forest, adding shade and texture to the route.

The refuge sits peacefully in the Marcadau valley, surrounded by grass, water and wide skies. It is a welcoming place to rest, with the feeling of being properly settled in the mountains.

Refuge du Wallon-Marcadau - Refuge des Oulettes de Gaube

Duration: 04:30 h
Distance: 9.58 km
Ascent: 830 m

The atmosphere shifts again as the route heads deeper into high mountain terrain. The surroundings feel quieter and more remote, with long stretches above the forest line.

The trail climbs steadily past alpine streams towards Lake Arratille, framed by rugged slopes and distant peaks. The walking is consistent and clear, with gradual height gain and expansive views that stay with you for hours.

The refuge below the Gaube basin is set in a dramatic landscape of rock and open ground. With steep walls rising behind it, this is one of those places where the mountains feel close and powerful as the evening settles in.

Refuge des Oulettes de Gaube - Chalet du Clot

Duration: 02:05 h
Distance: 8.71 km

This stage offers a softer rhythm after the higher terrain of the previous days. The walking feels relaxed, with more downhill and a gentler pace through wide valleys.

The path descends steadily, following streams and open slopes with views across the surrounding ridges. Alpine scenery slowly blends into greener pastures, and the trail becomes smoother underfoot.

The chalet appears in a grassy setting, simple and inviting. It is an ideal place to unwind, with a calm atmosphere and the sense that the hardest climbs are now behind you.

Chalet du Clot - Cauterets

Duration: 02:45 h
Distance: 8.87 km
Ascent: 90 m

The final walk brings a gradual return to the valley and a familiar world. The mountains slowly step back, giving space to forests and flowing water.

The route follows easy paths through woodland and along streams, mostly descending with occasional open views back toward the higher peaks. It is comfortable walking that allows time to look back and take it all in.

Arrival in Cauterets feels lively and satisfying. After days in the mountains, cafés, terraces and warm showers mark a smooth and well-earned finish.
