Southeast of Waialee near Kahuku on Oahu, the Kahuku Motocross Park has a rolling red dirt track with whoops, tabletops, triples and doubles. There is also a peewee track for 50cc bikes. In addition to the tracks, there are over 50 trails spread over 400 acres to explore on trail bikes.
South of Hilo on the Big Island, the Kulani Forest has a network of informal trails and old roads. The routes pass through lush, dense forest with giant ferns and huge stands of 60 foot tall eucalyptus trees. There is a 6 mile loop, though it can be difficult to follow with several new side routes that have formed.
Southwest of Hilo and southeast of Mauna Loa on the Big Island, there is a 8.2 mile one-way route along an old 4WD road heading up Mauna Loa that is open to dirt biking. This 4WD road eventually connects with the historic Ainapo Trail leading to the summit (foot traffic only). The 4WD road starts at 2,600 feet and climbs to 5,500 feet.
