The bio-pool was originally a pond, situated next to the mountain hut, which served as a watering place for animals grazing in the pasture.

This natural pool is a small aquatic ecosystem blending harmoniously with the landscape and the flora and fauna which are typical of the area.

To ensure proper filtration of the water, the pool has been divided into two areas, a regeneration section and a section for bathing. A small waterfall ensures that the water is oxygenated and energized, while a recycling system fed by a pump and drainage pipes maintains phytopurification at a high level. The water is clear and without chlorine odour, and its vitality and scent, much appreciated during summer dips, give the feeling of being truly immersed in nature in a blissful atmosphere.
