At the entrance to the Orlu national nature reserve, the valley brings together a park dedicated to wolves, a large treetop adventure park and the start of the walks to the Étang de Naguilles. A full day in nature, about 7 km from Ax-les-Thermes.
It is a park entirely devoted to wolves: several packs live in large enclosures, including European, Canadian and Arctic wolves. An observation tunnel lets you see them up close.
Activities, workshops and themed trails complete the visit, which children love. A snack restaurant is listed on site. Opening depends on the season: check the dates and times before setting off.
