Caribbean Spa at Pier House Resort

Caribbean Spa sits inside the Pier House Resort at One Duval St, right where Key West's Old Town meets the water. It's a hotel spa in the strict sense—access is limited to resort guests, and every treatment needs a reservation in advance. The minimum age is 14, with anyone under 18 required to have an adult with them, which keeps the vibe geared toward adults and couples rather than families.

Couples treatments are a core offering here, delivered in rooms built for two, alongside more standard massage and facial services. The spa runs Tuesday through Saturday from 9 a.m. to 5 p.m., with shorter Monday and Sunday hours of 9 a.m. to 2 p.m. If a service needs to be canceled or moved, the resort asks for at least 24 hours' notice—otherwise you're billed the full price of the booking.

As an upscale hotel spa, pricing sits in the higher tier typical of resort properties in Key West, though exact rates aren't listed publicly and are best confirmed when booking. The spa also offers gift certificates that can be customized for specific services, useful if you're planning ahead for someone else's visit. For logistics like phone booking or email confirmation, reaching the spa directly through its listed contact channels is the most reliable route before arrival.
