The Spa at Sea Island's 23 treatment rooms, including two spacious suites for couples or intimate gatherings of friends, provide venues for an array of massages, body treatments, skin care, and salon services that range from the All the Right Moves treatment – Spa at Sea Island's signature massage combining Thai, Lomi Lomi, and Swedish techniques – to The Remedy – a Balinese, spice-based body treatment that promotes digestion and improves circulation. To further customize the spa experience, guests can opt to listen to either upbeat or downbeat music during their treatment, depending on whether they want a lively or serene atmosphere. Each private spa suite features a full-sized soaking tub, balcony, stained glass windows, and beautifully appointed furnishings.

For guests seeking an invigorating workout, the state-of-the-art fitness center houses an indoor pool, the latest in Precor cardio equipment, and three squash courts. Five studios are dedicated to fitness, Pilates, yoga, cardio, and strength and personal training. The spa and fitness center experience supplements the active lifestyle encouraged by Sea Island's extensive sporting life, which includes world-class golf on three championship courses, tennis, paddleboarding, fishing, salt marsh kayaking, and trap and skeet shooting.
