What to know before you go
Honolua Bay is a deep, narrow bay on Maui’s northwest coast, designated as a Marine Life Conservation District. The bay is framed by steep, jungle-covered cliffs and opens to the north-northwest. In summer, the protected inner bay provides some of Maui’s best snorkeling, with spinner dolphins, green sea turtles, and dense schools of reef fish. In winter, the bay transforms into a world-renowned right-hand surf break.
The bay bottom is a mix of rock, coral, and patches of sand. The inner bay is relatively shallow (5–15 feet), while the outer bay where the surf break is located drops to 20–40 feet. A stream enters at the head of the bay, and after heavy rain it carries red Maui dirt and debris into the water, reducing visibility to near zero and creating a murky plume that can take days to clear.
As a marine preserve, all fishing, collecting, and removal of marine life is prohibited. Snorkeling and diving are the primary activities. The taking of any coral, shells, or marine organisms carries significant fines. The preservation status has resulted in an unusually dense and healthy reef ecosystem compared to unprotected bays on Maui.
North swells funnel into the bay, creating a world-class right-hand surf break that attracts professional surfers. The entire bay becomes a churning mass of whitewater during large swells, and snorkeling is completely out of the question. Currents strengthen dramatically, and even standing on the boulder beach puts you at risk of being swept in by rogue sets. Winter rainfall makes the access trail treacherous. Water temperatures drop to 75–76°F.
The bay calms to mirror-flat conditions, offering some of the most spectacular snorkeling on Maui. Visibility can reach 50+ feet on calm, clear days. Spinner dolphins regularly enter the bay in early morning. Water temperatures reach 79–80°F. Arrive early — the bay gets crowded by mid-morning, and parking along the road fills quickly. Check conditions before entering, as even summer can bring residual swell that creates currents in the bay.

Everyone in winter: The bay is a surf zone from November through March. Do not enter the water for any reason unless you are an expert surfer who knows this break. Even standing on the boulder beach during large swell events carries risk of being swept into the water by rogue wave surge.
Summer snorkelers: Enter carefully over the slippery boulders. Stay in the protected inner bay and do not drift toward the bay mouth where residual currents can be stronger. Watch for boats entering the bay, as this is a popular dive boat destination. Wear reef shoes and bring your own gear — there are no rental facilities at the bay.
Hikers on the access trail: Wear proper shoes with traction. The trail is steep, muddy, and unimproved. After rain it becomes dangerously slippery. Carry minimal gear to keep your hands free for balance. The trail back up is strenuous, especially after a snorkel session.
After heavy rain, bacteria and pollutants from runoff contaminate coastal waters. Wait at least 72 hours after heavy rain and until the water clears before entering. This applies to Honolua Bay and every beach in Hawaiʻi.
