Hanauma Bay Nature Preserve

About

Hanauma Bay Nature Preserve sits within a volcanic crater on Oahu's southeast coast, creating a sheltered turquoise bay that's home to over 400 species of fish and thriving coral reefs. It's one of Hawaii's most beloved natural treasures and a must-visit for anyone exploring the island.

The bay formed thousands of years ago when the sea breached the wall of a volcanic cone, flooding the crater and creating a curved, protected shoreline. Today it serves as both a marine life conservation district and a public beach park, drawing visitors who come to snorkel among green sea turtles, parrotfish, and butterfly fish in remarkably clear water.

Before heading down to the beach, every visitor watches a short educational film about the bay's ecosystem and how to protect it. This isn't just a formality. Hanauma Bay was once severely damaged by overuse, and the preservation efforts that followed have turned it into a conservation success story. The reef is recovering, and the fish populations are thriving.

A reservation is required to visit, so plan ahead. You can book online, and entry slots fill up quickly, especially during peak season. The preserve is closed on Mondays and Tuesdays to give the bay a rest from human activity.

From the upper parking area, you'll enjoy panoramic views of the bay that are breathtaking on their own. A tram runs between the lookout level and the beach below for those who prefer not to walk the steep paved path. Down at the beach, you'll find calm, shallow waters near the shore that are perfect for beginner snorkelers, while more experienced swimmers can explore the outer reef.

Snorkel gear is available for rent on-site, and the beach has lifeguards on duty. Pack reef-safe sunscreen, as traditional sunscreens containing certain chemicals are banned in Hawaii to protect marine ecosystems. Arriving early gives you the best chance at calm waters and good visibility.

Whether you're snorkeling for the first time or returning for another look at this underwater paradise, Hanauma Bay delivers an experience that connects you to Hawaii's ocean in a profound and personal way.

Accessibility

Hanauma Bay Nature Preserve provides several accessibility features for visitors with mobility needs. ADA-accessible restrooms and pathways lead to the beach lookout area, offering stunning views of the bay without requiring a trip down to the shore.

All-terrain wheelchairs are available from the Beach Information Kiosk on a first-come, first-served basis. These chairs are designed for sand and uneven surfaces, making beach access possible for visitors who otherwise couldn't reach the shoreline. They're available year-round from 8 a.m. to 4 p.m. For more information or to check availability, call the 24 Hour Information Hotline at (808) 396-4229.

A tram service runs between the upper level and the beach, which is helpful given the steep grade of the access road. Visitors with disabilities should request any specific accommodations a minimum of 48 hours before their visit date.

Some tour operators serving Hanauma Bay offer ADA-equipped vehicles with wheelchair lifts, though not all do. Confirm accessibility features when booking any transportation or tour package.

The upper viewing area with its paved pathways is the most accessible part of the preserve and provides excellent views of the bay and reef. Parking is available in the upper lot near the visitor center.

Contact Hanauma Bay directly at (808) 396-4229 for current details on accessible parking spaces, beach wheelchair availability, and any additional accommodations they can arrange for your visit.
