Foster Botanical Garden
Some of the trees in this botanical garden, which opened in 1931, date from 1853, when Queen Kalama allowed a young German doctor to lease a portion of her land. More than 150 years later, you can see these trees and countless others along with bromeliads, orchids, and other tropical plants, some of which are rare or endangered. Look out in particular for the cannonball tree and the redwood-size quipo tree. A docent-led tour is available every day at 10:30 am (call for reservations).
