Grand Hyatt Kauai Resort & Spa Rating: 4.5 Pearls
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.

Marriott Kauai Resort And Beach Club Rating: 4.0 Pearls
The Marriott has an unbeatable lineup of great features for a midpriced Kauai hotel, the Alexander Day Spa and Salon among them. The spa offers a full menu of massages -- given indoors or in an outdoor cabana -- waxing, body treatments, manicures, and haircuts and styling. Treatment prices are the most reasonable on the island: A 25-minute massage is $65, compared to $105 at the Grand Hyatt. It's a day spa, though, so there are no facilities beyond the four treatment rooms.

Kauai Beach Resort Rating: 3.5 Pearls
This Hilton's natural beauty and serene atomosphere provide a perfect setting for the Hawaiian Rainforest Spa, which blends traditional Hawaiian healing arts with modern techniques. Its body care, massages, and facial and eye treatments range from $115 to $150 for 50 minutes. It's a small space, though, with only four treatment rooms (none outdoors), a sauna, and two locker rooms.
