A dramatic descent from a cliff-top lookout down into a remote valley with a black sand beach on the Kohala Coast. The lookout alone offers one of the most stunning views on the Big Island with rugged green cliffs plunging into the ocean. The trail down to the beach is about a half mile but steep and muddy. At the bottom, the wild black sand beach is backed by dense forest and ironwood trees. The swimming is dangerous due to currents but the beach and valley scenery are incredible. The hike back up is a good workout.

Punalu'u Black Sand Beach

A jet-black sand beach where Hawaiian green sea turtles regularly haul themselves onto the sand to rest. Kids are amazed seeing these ancient creatures up close, basking just feet away on the dark sand. The black sand is made of volcanic basite and feels unlike any beach they have ever been to. The swimming conditions are often rough so this is more of a wildlife viewing and wading beach than a swimming beach. A small park with shade trees and picnic tables makes it a comfortable stop. Always maintain the required 10-foot distance from the turtles.

A protected beach park on the Hilo side with calm tide pools, a black sand beach, and an excellent chance of swimming with sea turtles. The lava rock forms natural pools that are sheltered from waves making it safe for kids to snorkel and explore. Green sea turtles feed on the algae growing on the rocks and sightings are almost guaranteed. The park has restrooms, showers, and lifeguards. The tide pools are fascinating for younger kids who can find sea urchins, crabs, and small fish. This is the best family snorkeling spot near Hilo.

A dramatic black sand beach surrounded by sea caves, lava tubes, and blowholes on the Road to Hana. The jet-black sand contrasts with turquoise water and green jungle creating otherworldly scenery. Kids are fascinated by exploring the lava tubes and sea caves along the coast. A short coastal trail leads to blowholes and natural rock arches. The beach itself has strong waves so swimming requires caution but wading at the edges is fine. The park also has cabins and camping for overnight stays.
