Our Marine Course

Our emblematic Marine Course has a new aquatic space with 400 sq.m. where everything has been thought out for your wellbeing. From soothing bubbles to relaxing seawater jets, you will be immersed in an ocean of wellness while enjoying the many benefits of seawater.




9 marine activities 

Multitonic jets, soothing bubbles, relaxing geysers, swan neck and powerful water wave, comforting indoor jacuzzi, invigorating cold water corridor, enjoyable aquabeds… and of course our outdoor jacuzzi with its magical view of Belle-île-en-mer.

This Marine Course is the most complete thalassotherapy treatment thanks to these 9 activities and jets, based on the natural benefits of seawater.
