La Grée des Landes

A treehouse cabin perched on stilts beside an old cypress is the headline room at this eco-minded boutique hotel on a forested hilltop near La Gacilly. The whole place leans into its Yves Rocher roots: organic gardens feed the on-site restaurant, and the spa's flower baths pull blooms from the surrounding fields. Guest rooms open onto private patios; the spa has a hammam and a light-filled indoor pool. It holds a Michelin Key.
