“King’s Pond,” Four Seasons Resort Hualalai, Big Island, HI

8 of 22

Why It’s Cool: The resort’s 1.8-million-gallon rock “aquarium” pool is inspired by Hawaii’s traditional anchialine ponds, landlocked bodies of water with subterranean connections to the ocean. Natural springs and ocean water feed into this man-made version, where guests swim alongside over 75 species of tropical fish and a spotted eagle ray.

Interesting Fact: The pool is sculpted out of 200-year-old lava rock.
