The Best New Hotel Spas in the World

"This $55 million spa is so different from its predecessor that it’s not even fair to call it a renovation. The Grand Wailea’s previous spa felt like a back-up plan for rainy days, but this new iteration, now the largest in the state, feels like a destination unto itself. Treatment rooms face the ocean, open air hydro baths let you capture the scent of flowers on the breeze, and bananas plucked from the on-site trees are offered as relaxation room snacks. No detail here is overlooked—down to treatments’ use of essential oils crafted by a woman on the island named Loleilani who grows botanicals according to the lunar cycles."
