An hour's drive from Nice, this two-floor getaway is classically beautiful (marble columns flanking a black marble pool, floor-to-ceiling arched windows) and designed to compete with the wild outdoor charms of the French countryside. Developed by ESPA, the dramatic 34,000-square-foot spa has extensive water features, including saunas, steam rooms, a laconium, and an outdoor hydrotherapy tub. Treatments make use of local ingredients such as Camargue sea salt, olive oil, and lavender as well as products from French brand Terraké—a welcome discovery for jaded global spa addicts, as is the spa café. With their own whirlpools, the couples suites ($818) are worth the splurge (massages, $195–$218).
