Monte Carlo’s oldest spa completed a head-to-toe makeover of its own in November. The Thermes Marins Monte-Carlo (thermesmarinsmontecarlo.com), which first debuted above Port Hercule in 1895, reopened following an eight-month transformation that added nine treatment rooms, a sauna-and-hammam complex, and Europe’s first cryotherapy facility. Innovative wellness programs curated by more than 28 specialists include such therapies as the 60-minute Human Tecar Reset (which claims to increase metabolism with the use of radio waves) and the 30-minute Reneve Mesopor (employing electronically charged applicators to minimize wrinkles). Before and after treatments, visitors can soak in the renovated saltwater swimming pool beneath a ceiling shaped like a giant seashell and dine on healthy Mediterranean cuisine at L’Hirondelle. For guests of the neighboring Hôtel Hermitage, the spa added a new VIP entrance, located just off the hotel lobby.
