At this beautiful hook-shaped beach with a mix of black lava, white coral and wave-tossed shells, the water is usually too cloudy for snorkeling, but just standing on shore you'll see honu (green sea turtles). You may spot more honu munching on limu (seaweed) around the ancient ʻAiʻopio fishtrap, bordered by a Hawaiian heiau at the beach's southern end. Inland are anchialine ponds – pools of brackish water that make unique habitats for marine and plant life.
To get here, turn right into the first parking lot at Honokohau Harbor (look for the small public coastal access sign). Near the end of the road is the signposted trailhead; a five-minute walk on a well-beaten path leads to the beach. You could also take the more scenic, if longer, route by hiking to the beach along the 0.75-mile Ala Hele Iki Trail from the visitor center.
