"On the Kona-Kohala coast of the Island of Hawai‘i, the Four Seasons Resort Hualalai is a sprawling 800-acre resort with 249 rooms and suites with beds fashioned out of Hawaiian textiles and bamboo, dark wood shutters, marble bathrooms, and lava-rock outdoor showers. On property, King’s Pond is so much more than a swimming pool: It doubles as marine reserve of 1.8 million gallons of brackish water with some thousand fish, plus a resident spotted eagle ray. Guests can swim in the semi-natural pool, which was carved out of lava rock with a sandy bottom. Those curious to learn more about the marine life at King’s Pool can tap one of the resort’s five resident marine biologists, who lead private eagle ray feedings and junior marine biologist experiences." - Kathryn Romeyn
