What to expect: Inspired by its environment, the hotel set architectural trends when opened by businessman and conservationist Laurance S. Rockefeller in 1965. Its open-air, blue-tiled entryway has sand-colored concrete and seven-story palm trees. Staff and guests here include multiple generations of families.

Amenity highlights: Mauna Kea's golf course (renovated December 2008) is built over black lava rock, and golfers can still tee off over an ocean inlet at the third hole. Public spaces feature 1,600 Pacific and Asian artworks from founder Laurance Rockefeller's private collection—including one of only three known 7th-century pink granite Buddhas from India. Lifeguards watch swimmers, snorkelers, and sailors at the hotel's white-sand crescent beach, and the large pool has an ocean view. Guests can choose from excursions, craft classes, lu'aus, and many recreational activities.

Insider tip: Mauna Kea guests enjoy the amenities of the resort's companion, the Hapuna Beach Prince Hotel, which includes a golf course designed by Arnold Palmer and Ed Seay. A shuttle between Mauna Kea's hotel, oceanfront tennis courts, and golf course; and Hapuna Beach's lobby, golf clubhouse, and fitness center departs every 20 minutes.

What to expect: Set on 32 acres of oceanfront lawns and gardens, this six-story Fairmont has a lofty, marble-floored lobby that opens to a sunset deck overlooking a 10,000-square-foot freeform pool, tropical gardens, and Pauoa Bay. Families and leisure travelers are drawn to the resort for its ocean activities, tennis facilities, and proximity to two 18-hole championship golf courses.

Amenity highlights: Beach activities include snorkeling and sailing aboard a 35-foot traditional Hawaiian outrigger canoe (surcharge). A secluded outdoor spa with waterfall cabanas features Hawaiian-inspired treatments (surcharge). Dining options include two restaurants specializing in fresh seafood and regional cuisine, a sushi bar, and a takeout deli. The resort's Tennis Pavilion offers 10 Plexipave courts (surcharge), a pro shop, and professional instruction (surcharge). Complimentary shuttle service within the Mauna Lani Resort is available upon request.

Insider tip: A 25-minute drive from the resort, in the town of Waimea, Parker Ranch is one of the oldest and largest cattle ranches in the United States. Founded in 1847, the ranch covers 175,000 acres. The museum and visitor center traces the history of the Hawaiian cowboy, or paniolo. Visitors can tour the ranch via horseback, wagon, or ATV (surcharge).
