Piau-Engaly is a winter sports resort in the French Pyrenees, located in the commune of Aragnouet, in the Hautes-Pyrénées department and the Occitania region.

Piau-Engaly is located in a large cirque, at the top of the Vallée d'Aure, in the French Pyrenees.

The Bordeaux architect Jean Marc Vialle, in association with Philippe Sanchez, was the project manager.

Shops, services and access to the slopes are grouped together in a partly underground circular complex in the centre of the resort, at an altitude of 1,860 m (6,100 ft).

In 2018, the architectural firm of Jean Michel Wilmotte was asked to participate in the renovation and construction of new accommodation.

[2] As part of the "Natura Piau" project, a four-star tourist residence was designed to fit in with the existing architecture.

The resort has a snowpark adapted to all levels of ability and allows for snowshoeing, dog sledding, snowtubing and tobogganing.
