Kuilau Ridge Trail
Kuilau Ridge Trail is just opposite the Keahua Arboretum on Highway 580, Kuamoo Road, 5½ miles above Wailua. This is a 2.4-mile, two-hour round-trip moderate uphill hike to a picnic shelter. The rest stop overlooks the surrounding tropical rain forest and mountains. Take some time to wander through the arboretum to enjoy the mountain views and exotic trees and plants. This is a good mountain biking trail also.
