Black Rock, known locally as Puʻu Kekaa at the north end of Kaʻanapali Beach, may be Maui's most popular snorkel location, but also considered one of Hawaii’s most hazardous snorkeling sites. Retired Maui Fire Department ocean safety chief Colin Yamamoto described it as “by far, the No. 1 drowning capital in Hawaii.” From 2009-2018, Maui recorded 94 snorkeling-related drownings, and Black Rock alone accounted for 18 visitor fatalities—more than any other beach on the island. Strong, unpredictable currents catch tourists off guard, including the temptation to snorkel into deeper waters around the rocks. There are no lifeguards at this beach.
Snorkeling is the leading cause of ocean drownings among tourists in Hawaii, even surpassing vehicle accidents and falls. The lack of safety infrastructure—no staffing, no signage—turns a visually appealing spot into a dangerous location for those unaware of its perils.
Safety Tips: Avoid snorkeling at Black Rock unless you're an experienced swimmer and well-equipped. Remember that snorkeling is a strenuous activity! If you choose to snorkel here go in the morning (before trade winds pick up and create more difficult conditions - typically before 11am), stay close to shore, snorkel with a buddy, wear a flotation vest, and check ocean conditions beforehand. Also take a moment to familiarize yourself with an unusual health condition called ROPE (rapid onset pulmonary edema), which may be triggered when snorkeling within a couple days of taking a long flight.
