Cross one off the bucket list and swim with dolphins! The experience offered by Dolphin Quest is as cool as it sounds, especially if you’re a huge fan (and who isn’t?) of these playful, hyper-intelligent marine mammals that’ve bonded with us human types for centuries. Even if you don’t book a dolphin encounter yourself (they take reservations up to one year in advance) all encounters are visible to the general public from a lawn overlooking the lagoon. Dolphin Quest is hosted by Hilton Waikoloa, but you don’t need to be a guest of the hotel to book some awesome quality time with a dolphin.
