Hanauma Bay, located on the southeastern shore of Oahu, is one of the most popular snorkeling spots in Hawaii. The protected natural preserve is part of a volcanic crater just south of Waikiki and offers stunning views of tropical marine life. Because it’s a protected area, swimming and snorkeling here will generally reveal a greater variety of fish than some other areas around Hawaii. Visitors to Hanauma Bay can expect to spot numerous species such as parrotfish, butterflyfish, angelfish, Moorish idols, beaked cornetfish, surgeonfish, emperor angelfish, goatfish, and many more. There are also sea turtles that can be seen at times. In addition to the vibrant colorful fish and corals that make up this underwater world, there are plenty of mollusks like octopuses and nudibranchs found in tide pools along the rocky shores. The bay is very deep (up to 30 meters) so you can expect to find interesting creatures at various depths throughout your exploration.

Traveler’s Note: The best time for snorkeling at Hanauma Bay is early morning hours as it’s less crowded then and visibility tends to be better due to calmer waters. Additionally, if you’re lucky you may even catch sight of rare or endangered species like Hawaiian monk seals or green sea turtles at the bay!
