Hogolo thermal bath is a thermal bathing facility drawing on geothermal spring waters to provide mineral water bathing and wellness services in the tradition of its regional spa culture, offering guests the restorative experience of naturally heated mineral water in a setting that honours the thermal heritage of its location. The facility provides warm mineral pools and spa treatments designed to deliver the simple pleasures of thermal bathing — warmth, relaxation, and a sense of renewal — in an environment of comfort and professional care.

Insider tip — The Hogolo Gallo-Roman thermae at Plestin-les-Grèves are the 2nd-century remains of a complete Roman bath complex — one of the most intact ancient thermae in northern France, overlooking the Bay of Lannion on the Breton coast. The Romans built these baths above a granite spring in a practice of coastal thermal bathing that directly anticipates the modern thalassotherapy tradition of Brittany, where Atlantic seawater and mineral springs have been combined for healing for nearly two millennia.
