Mountain bike access in this area is under constant scrutiny and will only continue if bikers avoid skidding corners and respect other trail users.
This is a challenging singletrack with awesome views of the west coast of Oahu and the Pacific Ocean beyond. It's a technical singletrack and, at times, there is some exposure, so don't become overly preoccupied with the views. There are a couple places where even the most advanced riders will likely have to dismount, and a few more places where the rest of us mortals will be hiking.
From east to west, the Kuaokala Ridge Trail descends towards its terminus near the Kaena Point Satellite Tracking Station (which will be to the left (west) on the paved road). The alternative road to the station from the west coast, requires a permit from the Division of Forestry and Wildlife and will require passing multiple guard stations.
