Snorkeling at Hanauma Bay

Hanauma Bay is widely regarded as one of the best snorkeling spots in Hawaii, offering an unparalleled underwater experience for visitors of all skill levels. As a protected marine sanctuary, the bay is home to a thriving ecosystem of tropical fish, coral reefs, and the iconic Hawaiian green sea turtle (Honu). Whether you're a first-time snorkeler or an experienced diver, Hanauma Bay provides the perfect setting to explore Hawaii’s vibrant underwater world.

What Makes Snorkeling Here Unique?

One of the standout features of Hanauma Bay is its calm, shallow waters, which make it an excellent snorkeling destination for both beginners and experienced adventurers. The bay’s crescent-shaped coastline, formed within a volcanic crater, shelters the waters from strong currents, ensuring a safe and enjoyable snorkeling experience. With exceptional water clarity, snorkelers can easily spot an array of colorful fish, sea urchins, and living coral formations just a few feet from shore.

Hawaiian Green Sea Turtles & Vibrant Coral Reefs

Hanauma Bay is one of the best places on Oahu to encounter the Hawaiian green sea turtle. These gentle giants, often seen resting on the seafloor or swimming near the reef, are a true highlight for visitors. In addition to turtles, the bay’s ecosystem is teeming with brightly colored coral reefs, which provide a habitat for hundreds of tropical fish species, including the famous Hawaiian state fish, the Humuhumunukunukuāpuaʻa.

Snorkeling Tips for Beginners & Experienced Snorkelers

For Beginners

Stay in the shallow areas near the shore, where the water is calm and the fish are abundant. Practice using your mask and snorkel in waist-deep water before venturing further. Move slowly and avoid standing on the reef to protect the delicate coral ecosystem.

For Experienced Snorkelers

Explore deeper sections of the bay for a chance to see larger marine life and more intricate coral formations. Swim along the outer reef for a wider variety of fish species, but be mindful of changing currents and always snorkel with a buddy.

General Snorkeling Guidelines

Always use reef-safe sunscreen to protect the environment, maintain a safe distance from marine life, and respect conservation rules by not touching the coral or sea creatures.
