Nani Mau Gardens
Wide walkways are accessible to wheelchairs; take a self-guided tour or a 20-minute narrated tram ride ($8). Every flowering plant in Hawaii is represented here, they say. Highlights include the perfectly manicured Japanese gardens and the dazzling collection in the orchid house. Other features include an art gallery, an all-you-can-eat restaurant, and, oddly enough, a hair salon.
