What: A sanctuary on its own private island separate from the One&Only Cape Town hotel, with ten serene treatment rooms, his-and-hers hydrotherapy (including vitality pool and experience showers), a Bastien Gonzalez mani-pedi studio, and a yoga pavilion.
The look: Sleek, contemporary, and pared down (some may say severe), saved by earthy tones, textured surfaces, wood floors, and exposed roof trusses. The overall effect is calming rather than engaging.
Who goes: Hotel guests escaping their kids, and visiting A-listers, including Robert De Niro and Martha Stewart.
The treatment: The two-hour Essence of Earth and Ocean Experience uses Khoisan salt for the full-body scrub, a seaweed and algae body wrap, and hot shells for massaging.
P.S.: Arrive an hour early to enjoy the hydrotherapy facilities (massages, $94-$120).
