Spa Sirène is our in-house spa on the lower ground of The Royal Yacht, designed around the rhythms of the sea and the island it sits on. A heated vitality pool, Swedish sauna, aromatherapy steam room, salt inhalation therapy and experience showers combine with a fully equipped gym and a tranquil rest room with thermal couches. Complimentary use of the facilities is offered to hotel guests aged 16 or over and to anyone spending a minimum of £90 on treatments. Our therapists work exclusively with Phytomer from St Malo and Aromatherapy Associates, two brands that reflect our coastal setting and our belief in natural, effective skincare.

Our specialised hydrotherapy pool designed for relaxation and muscle recovery
Between treatments, retreat to our tranquil rest room with heated thermal couches. Phones off, voices low, this is the quietest corner of the hotel.
Deeply relaxing, saunas eliminate toxins through the skin, stimulate blood flow and boost the immune system. Stay no more than 15–20 minutes at a time.
Pull the rope and a bucket of ice-cold water tips overhead before refilling itself, the ideal finish after a session in the sauna.
Warm, pressurised jets ease tension in the back, shoulders and legs, an ideal after-gym session or a restorative stop between treatments.
Warm salt steam helps induce deep, calm sleep, banishes stress and fatigue, and supports relief from eczema, cramps and headaches. We recommend 20–30 minutes followed by a refreshing shower and 20–30 minutes of rest.
Soak your feet in warm, bubbling water and enjoy a new relaxing experience, leaving you feeling refreshed and revitalised
The body heats gently as an automated jet of aromatic steam stimulates circulation and starts a purifying, detoxifying process. The ideal session is 15–20 minutes
Combine heat treatments with a three-mode shower. Caribbean Rain, Fresh peppermint mist, or the classic hot-to-cold Atlantic Ocean cycle
