Spadium Saint-Grégoire is a public aquatic centre just north of Rennes with a 60 m lazy river, hot tubs, a sports pool and a slide. Its separate Espace Détente has a Finnish sauna at 80 to 110 degrees, an infrared Japanese sauna at 55 degrees, hammams, Scandinavian showers, a rest room and a patio with a terrace and a cold-water bath. The Détente ticket excludes the jacuzzis, which need the Détente plus pool entry. The area can be hired privately on Saturday afternoons.
