Keahua Forestry Arboretum offers a variety of plant life from monkeypod and eucalyptus trees to exotic mango. The park has several picnic pavilions to relax on and fresh swimming pools and streams to cool off on a hot day. Several of the island's popular hikes like the Kuilau and Powerline trails begin here. You may also catch a glimpse of Mt. Wai'ale'ale if it is not wearing its customary robe of clouds.
