Lyon Arboretum

Tucked into the upper reaches of the valley, this University of Hawaiʻi research arboretum centers on the study and conservation of tropical flora. Alongside active research facilities and community education programs, the grounds cultivate extensive living collections of palms, heliconias, gingers, and native Hawaiian species. Paths track past the ʻAihualama Stream, drawing visitors who value its deep greenery and quiet, tranquil atmosphere.
