Kilauea Point National Wildlife Refuge and Kilauea Lighthouse
A beacon for sea traffic since it was built in 1913, this National Historic Landmark has the largest clamshell lens of any lighthouse in the world. It's within a national wildlife refuge, where thousands of seabirds soar on the trade winds and nest on the steep ocean cliffs. Seeing endangered nene geese, white- and red-tailed tropic birds, and more (all identifiable by educational signboards) as well as native plants, dolphins, humpback whales, huge winter surf, and gorgeous views of the North Shore are well worth the modest entry fee. The gift shop has a great selection of books about the island's natural history and an array of unique merchandise, with all proceeds benefiting education and preservation efforts. www.fws.gov/kilaueapoint.
