Wai'anapanapa State Park
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.
