Koko Crater Botanical Garden occupies part of a large crater on the eastern side of Oahu. The city set the crater aside for garden development in 1958. Its plant collections fill the inner slopes and basin, and the garden concentrates on rare and endangered dryland species. Xeriscape methods shape the dry landscape so desert-type plants can thrive. A self-guided loop of about two miles winds through the garden, and visitors should expect uneven, rocky footing, bring their own water, and plan on roughly an hour and a half. Guided group visits can be arranged by appointment.
