Anantara Spa, Qasr Al Sarab, Abu Dhabi, United Arab Emirates
What: A sand-colored villa within the Arabian fortress-style Anantara Resort amid the Empty Quarter's towering dunes, with five treatment rooms, a hammam, a sauna and steam room, and an ice cave.
The look: Gongs, dark wood, imported tropical flowers, and silk-clad Thai masseuses make the ambience more Asian than Arabian.
Who goes: Emirati and expat couples, older European tourists, and Arab Gulf businessmen and their dates.
The treatment: The Dawn Renewalwhich you can't actually have before 10 a.m.is a relaxing and invigorating combo of foot massage, detoxifying green tea scrub, and anti-jet lag rubdown.
P.S.: Make appointments before arriving at the resort; this small spa is in high demand (massages, $351).
