“G-Out trail is the lower, more technical part of the great combo with SideWinder trail.
— Andreas Boehme
You can either take SideWinder trail and then continue throughout the canyon where the trail turns into G-Out (close to wooden sign posting "Human Power Only please" or you may take a shortcut connector trail right from the fire road ~500 ft behind the "Towers".
Either way, you'll face some more technical, but still fun sections, a few natural wall-rides, ups and downs where the canyon narrows at some sections. At the trail end, keep left and start the fireroad climb back to Tapia Canyon Rd, where you might watch out for another nice descent on Dogtag trail (incl. Top-Dog)
or Kona singletrack.
