Hawanawana Spa.

Located within the Four Seasons Resort Lanai, Hawanawana Spa—meaning "whispering ocean"—is a cliffside sanctuary that draws heavily from its marine surroundings. The design favors an earthy, elegant aesthetic, utilizing marble-lined spaces and oversized windows that pull in the Pacific breeze. Treatments are deeply rooted in the island’s history, ranging from pineapple-citrus polishes that nod to Lanai’s plantation past to Algae Ti Leaf wraps. For a more intensive experience, the multi-hour Ocean Ritual utilizes wild seaweed and marine botanicals, while the Island Serenity Ritual integrates Ayurvedic practices like shirodhara. Beyond the eleven treatment rooms—which include four expansive couples' suites with private rain showers—the facility offers aerial yoga and a salon. It’s a sophisticated retreat where the sound of the surf serves as a constant, natural soundtrack.
