About Hanauma Bay Nature Preserve
Hanauma Bay Nature Preserve is a protected marine conservation district set inside a sunken volcanic crater on the southeast coast of Oahu. It is famous worldwide for offering some of Hawaii's finest and most accessible snorkeling in calm, shallow waters. The pristine bay protects a rich living reef that is home to hundreds of species of tropical marine life and native green sea turtles.
Don't miss
- Snorkel over the shallow inner reef to encounter colorful schools of parrotfish, tangs, and Hawaii's state fish, the humuhumunukunukuapua'a.
- Observe Hawaiian green sea turtles gliding gracefully through clear turquoise waters near the outer coral formations.
- Learn about marine conservation and bay history at the mandatory Marine Education Center orientation.
- Admire sweeping postcard views of the crescent-shaped bay from the scenic lookouts along the upper ridge.
Plan your visit
Early morning is the best time to arrive because winds are calmer, water visibility is at its clearest, and crowds are lighter. Visiting on weekdays also tends to offer a slightly more relaxed experience than weekends.
Admission is paid for non-residents, and timed entry reservations must be booked online in advance. Entry is free for Hawaii residents with valid local ID and for young children.
From Waikiki or central Honolulu, drive east along the H-1 freeway continuing onto Kalanianaole Highway (Route 72) for about 25 to 30 minutes. You can also catch a rideshare or take city bus route 22 directly toward the bay.
Tips for visiting
- Book your reservation the moment the online portal opens two days ahead, as time slots sell out in minutes.
- Wear only mineral-based reef-safe sunscreen to prevent toxic chemical damage to fragile coral reefs.
- Never stand on, kick, or touch the coral heads, as doing so kills live polyps that take decades to grow back.
- Maintain a respectful distance of at least 10 feet from sea turtles and other protected marine animals.
- Take the tram service if you want to avoid walking up the steep paved hill at the end of your visit.
Hanauma Bay Nature Preserve FAQ
Can I rent snorkeling equipment at the bay?
Yes, a rental concession on the beach provides masks, snorkels, fins, and life jackets for visitors. Lockers are also available on site to safely store your belongings while you swim.
Is Hanauma Bay good for beginner snorkelers and children?
The inner reef area is exceptionally well-suited for beginners and children because the natural barrier keeps the shallow waters calm. Lifeguards are on duty across the beach to monitor water safety.
What days is Hanauma Bay closed?
Hanauma Bay is typically closed to the public on Mondays and Tuesdays to allow the marine ecosystem uninterrupted rest. Be sure to check the current schedule when planning your trip to avoid arriving on a closure day.
Can I bring food and drinks to the beach?
Visitors are allowed to bring their own personal snacks and non-alcoholic beverages onto the beach in small coolers. A snack bar is also available near the upper entrance before you walk down to the shore.
