Lyon Arboretum
Manoa
Tucked all the way back in Manoa Valley, this is a gem of an arboretum operated by the University of Hawaii. Hike to a waterfall, or sit and enjoy beautiful views of the valley while having a picnic. You'll also see an ethnobotanical garden, a Hawaiian hale (house) and garden, and one of the largest palm collections anywhere—all within a parklike setting. Its educational mission means there are often regular talks and walks, plus classes on lei-making, lauhala weaving, Hawaiian medicinal arts, and more, which you can take for an additional fee.
