Punalu'u Beach is the Big Island's most well-known black sand beach, located at Highway 11's 56-57 mile markers between Volcano Village and Naalehu. The beach is a prime spot on the island for viewing endangered Hawskill sea turtles, though visitors should note that direct contact with turtles is illegal due to sensitive habitat concerns. Beautiful pitch-black lava sands line the beach, created from both old and new lava flows. Opportunities for swimming are available in calm water conditions, giving visitors a chance to experience the beach's unique dual-temperature waters created by underwater freshwater springs.

Snorkeling is permitted at Ninole Cove, and overnight camping is allowed with permits. Though parking and restroom facilities are offered, visitors should note that lifeguards are not staffed at the beach.
