Start up the access Maunawili-Waimanalo Access Road. You can take access road up and over the hill but we turned and took the trail to the right along the ridge line, which is marked as the Maunawili Ditch Trail. Sorry no photos..not the most scenic trail, this is more for the fun ride. It is a good entry ride for people who are new to mountain biking. Once you get to the end of the Maunawili Ditch Trail, take a right on Mahiku Place to return to where you started.
