Naupaka Spa & Wellness Center, Kapolei

Four Seasons Resort Oahu at Ko Olina is the portrait of tranquility. Towering palm trees and lush gardens line the property, with fronds providing guests with shade as they relax in one of the many outdoor lounge areas, taking in views of the Pacific Ocean's glimmering waters.

Aside from stunning scenery, the resort is home to Naupaka Spa & Wellness Center with indoor and outdoor pools and hot tubs, a eucalyptus steam room, and a sauna. The center takes advantage of these surroundings and amenities inside its 35,000-square-foot facility with indulgent Hawaiian-inspired treatments.

• Nõ ka 'oi: This service's name means "the best of everything," which is fitting, considering its myriad indulgent natural elements. In addition to an exfoliating sugar-cane and coconut-oil body scrub, Nõ ka 'oi includes a moisturizing coconut-milk and aloe body wrap, hair and scalp treatment, and lemongrass-ginger lomilomi massage.
• Papa lani massage: During this holistic massage, bodywork techniques are combined with Sodashi plant essences and ancient healing stones and crystals. The 80-minute session aims to leave clients relaxed and rejuvenated, with greater spiritual, physical, and emotional balance.
• Samadara ultimate age-defying facial: Designed to nourish skin and combat signs of aging, this facial employs both Ayurvedic healing traditions and natural healing energies. For example, a warm rose-quartz facial massage helps increase circulation, while Samadara's potent skincare formula works to promote collagen production, leaving skin more youthful in appearance.
