Maui Ocean Center, The Aquarium of Hawaii

14 Fun Things to Do in Maui With Kids | Condé Nast Traveler

"Although most people come to Maui to do their own snorkeling and diving, the Maui Ocean Center is a great way to show younger kids what actually lies beneath the ocean in Hawaii. This aquarium has a prime location on Ma‘alaea Bay, plus some completely jaw-dropping exhibits such as Open Ocean, an underwater tunnel where sharks, sting rays, and various fish swim overhead, as well as a turtle lagoon, a living coral reef, and an exhibit that touches on the cultures and traditions of early Hawaiians. It’s a popular attraction for families, sure, but it's somehow never too crowded." - Juliana Shallcross
