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.
Two easy 15-minute trails lead visitors throughout the park. To get to Keahua take Highway 56 north from Lihue. You will cross the Waimea River Bridge and then turn mauka onto Kuamo'o Road. The arboretum is 5 miles up the road.
