Four Seasons has run one of the most consistent hotel spa programmes in the world for three decades, and the yacht version is a direct transfer rather than an outsourced concession.
Treatment rooms are positioned outboard with sea views, a rarity at sea where spas are usually pushed inboard for space reasons. Couples' suites include private terraces.
The thermal area carries a sauna, steam room, experience showers and a relaxation deck open to the air, and is included rather than sold as a pass.
A wellness team of trainers, a nutritionist and visiting practitioners run classes on the pool deck and one-to-one programmes, with treatments deliverable in-suite at no surcharge.
What's included
- Sea-view treatment rooms including couples' suites
- Complimentary access to sauna, steam and thermal deck
- Daily fitness and movement classes on the open deck
- In-suite treatments at no delivery surcharge
- Visiting wellness practitioners on selected voyages
