The Hydrothermal Experience

Relax and unwind

Featuring the largest spa-hydrotherapy pool in the south west, heated up to a comforting
35C, this is the perfect place to work away stress and tension.
After a soak, stretch out on the poolside day beds and heated loungers, then cleanse your skin in the
herbal Finnish sauna and outdoor barrel sauna with views out across Falmouth Bay.
Bask in the thermal paradise of the rainforest steam room, then step into the world’s only
Cornish sea salt steam room and breathe in to relax your respiratory system.
Finally, sink into restorative bliss in the outdoor hot tub with views that stretch across the spa
gardens to the ocean beyond.

Our 2-hour Hydrothermal Experiences start from £50 per person

Hotel guests can access a discounted £40 Hydro Experience and Health Club members can enjoy the experience from £30.
