The Most Beautiful Spas in the World — and Which Treatments to Try!

Recommended treatments: Try the signature treatment, a 90-minute hot-and-cold Verbena massage ($192). It kicks off with a hot salt scrub, followed by a deep-tissue massage. It wraps up with a refreshing mist and chilled body gel so you can head out to the pool feeling detoxed. Or take advantage of the abundance of fresh immortelle flowers (a yellow bud known for its antiaging properties), which are included in the Secret of Youth facial ($137 for 60 minutes). The never-fading flower found on the island of Corsica will help give you a firmer visage.
