Best Hotel Spas in Hawaii

The 50,000-square-foot neoclassical Spa Grande is the biggest in Hawaii -- and one of the top-rated in the U.S., thanks in large part to its extraordinary baths. They include five aromatic pools, a Japanese furo bath, cascading waterfall, Roman hot tub, and Swiss jet shower. The spa offers more than 100 treatments, including locally inspired signature therapies like the Pala'au Journey ($225 for 80 minutes). Use of the facilities is $55 for two hours (or free with a treatment)-- more than most spas charge for a whole day.

Opened in January 2009, the Ritz-Carlton Spa is the newest spa on Maui. The large, 17,500-square-foot facility conducts treatments in spacious suites with private showers. The first-class facilities ($50 for a day pass) include whirlpools in tucked-away grottos, eucalyptus steam rooms, cedar saunas, and rain showers. Body treatments incorporating Hawaiian healing methods start at $155 for 50 minutes.

The 17,000-square-foot Moana Lani Spa is one of the largest and newest luxury spas in Waikiki. But what really makes it stand out is its prime location on Oahu's Waikiki Beach. The ocean views from its swank treatment rooms, including its couples treatment suites with private balconies, are superb. The extensive facilities include oceanfront relaxation lounges, steam rooms, saunas, and a Jacuzzi. Massages start at $120, body treatments at $75, and facials at $125. Day passes are $40.

The 46,000-square-foot Anara Spa is hands-down Kauai's biggest and best, with 11 treatment rooms, five couples massage huts in the garden, a sauna, stream room, and whirlpools, lava rock outdoor showers, a 25-yard lap pool, and its own restaurant, Kupono Cafe. The spa's award-winning treatments are inspired by la'au, the Hawaiian tradition of herbal medicine. The signature facial is $165 for 50 minutes.

Oahu's Kahala Spa offers an indulgent and -- most significantly -- very private spa experience. There are no common areas. Instead guests get the use of a 550-square-foot private suite for changing and post-treatment showering. Time in the infinity tub is included in some of the longer rituals, or can be added to any treatment for an additional fee. Massages start at $185, body treatments at $280, and facials at $220.

Guests who make the long drive to Maui's secluded east coast are rewarded with one of the island's best spas. All of Honua Spa's treatment rooms have private lounges facing the lush grounds. In keeping with the hotel's respect for local traditions, the treatments focus on Hawaiian techniques. Honua is also the best spa value on Maui: Guests have free use of the facilities, which include an outdoor lava-rock pool, cold plunge bath, stream room, and outdoor shower. Treatments start at a reasonable $140 for 50 minutes.

The JW Marriott's day pass is one of Oahu's best spa values. For $20, guests can use the 35,000-square-foot spa's eucalyptus stream room, sauna, and Roman-bath-style Jacuzzi. Massages and skin therapies range from $105 to $150.
