Cauterets - Refuge d'Ilhéou

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

Today, your journey begins in the charming spa town of Cauterets, where the scent of pine and the sound of waterfalls set the mood for adventure. The trail climbs gently at first before becoming steeper and rockier as you ascend through the Vallée d’Ilhéou. The scenery transforms quickly—wooded paths give way to alpine meadows and open rock faces where you may spot marmots or eagles soaring above.

After a final push, you reach the turquoise shores of Lac d’Ilhéou, nestled beneath jagged peaks. The Refuge d’Ilhéou sits right by the water, offering breathtaking views and a cozy atmosphere for your first mountain evening. Dinner at the hut is included.

Tip: Stroll around the lake before sunset—the golden light reflecting on the water makes for unforgettable photos. Bring a warm layer; nights at 1,988 m can be brisk even in summer.
