The Big Island (officially named Hawaii) is the largest island in the United States' Hawaiian archipelago in the Central Pacific. Its diverse terrain spans colored-sand beaches at Papakolea (green) and Punalu’u (black) to lush rainforest. Within Volcanoes National Park, there are 2 active volcanoes, Kilauea and Mauna Loa. Hapuna Beach and Kahalu'u Beach Park in the west are popular snorkeling sites. The island’s lush, wet eastern side has rainforest, the port town of Hilo, Hawaii Tropical Botanic Garden and Akaka Falls State Park. Western conditions are dry. There, high-end resorts dot the Kohala Coast, and the Kona region is home to coffee plantations. To the north is Waimea cattle country, at the base of massive, dormant Mauna Kea, and remote Waipio Valley is a major hiking spot. Cultural sites include Puako Petroglyph Archaeological Preserve, with lava-rock carvings, and Pu‘uhonua o Hōnaunau, a sacred burial ground and traditional place of refuge.
