The begining is part of a 4X4 playground but it is good for bike handeling and makes the first miles of warm up great. With the pacific ocean to your right keep riding until you come to the nature reserve and gate. Once there make sure to stay on the path, and ride it to the end. It splits halfway, the lower one is a nice ride but the upper one has a great view. Ride late in the afternoon to see a great Hawaiian sunset!
On Oahu: From Kamehameha Hwy turn onto rte 930 to Farrington Hwy and drive all the way to the end.
