The water is usually too cloudy for snorkeling at this beautiful hook-shaped beach with a mix of black lava, white coral and wave-tossed shells, but just standing on shore you'll often 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.
