B'O Resort Thermal Spa
About B'O Resort Thermal Spa
B'O Resort is a modern thermal spa complex built around northwestern France's only natural hot spring, where water emerges at 24.6°C after centuries of filtering through rock 400-500 meters underground. The 2,000 m² spa houses 40 hydrotherapy cabins and 17 treatment rooms offering hydromassage, thermal water showers, and specialized therapies for circulation, joints, and stress relief. Visitors receive a designer bathrobe by Gaspard Yurkievich and access to the thermal pool, sauna, vaporarium, and relaxation areas. The water's unique pH of 4.3 matches human skin, while trace elements like copper and molybdenum provide anti-inflammatory and cardiovascular benefits. The thermal tradition here dates to medieval times, with the spring's discovery attributed to the legend of Lord Hugues de Tessé, whose aging horse emerged rejuvenated from the waters. Open seasonally from February to November, advance booking is recommended for treatments.
Interesting Facts
The thermal water contains radon, a naturally occurring radioactive element that provides analgesic and healing properties. While radon in buildings is harmful, the controlled exposure in thermal water at low concentrations has been used therapeutically for over a century in European spas.
The spa pumps 48 cubic meters of thermal water per hour continuously from the underground source. This constant flow rate has remained stable for centuries, indicating a vast underground reservoir that scientists estimate took thousands of years to accumulate.
Between 1920 and 1935, Bagnoles-de-l'Orne was one of Europe's elite spa destinations, attracting royalty and politicians from across the continent. The town still preserves its Belle Époque architecture from this golden era, making a walk through the streets feel like stepping back in time.
