La Croix Valmer, twenty minutes from Saint-Tropez, is home to Lily of the Valley, a wellness-focused retreat whose tranquil atmosphere is a world apart from its more revelry-oriented neighbors. That’s not to say it’s not glamorous — with design by Philippe Starck, and a clientele that spares no expense in pursuit of self-care, it’s squarely in modern-luxe territory. There’s a lavish spa and a 25-meter outdoor pool; the splendid five-mile Gigaro Beach is just a few steps away, and the Vista restaurant, with its menu full of vegan and vegetarian options, looks out over the bay.
