From Wayside Canyon Rd.
stay to the left as you head out of the junkyard. The climb is steep and loose in some sections but is very ride-able for those in above average shape. For everyone else get ready for some hike-a-bike. The trail is a roller coaster working its way up and down across a ridge line.
When you make it to the top of the first climb you're rewarded with a steep technical downhill that has two distinct lines down it. One is loose, the other is full of braking bumps at the bottom. For less experienced riders you may want to walk down this or take Wayside Canyon Connector
to Tapia Canyon instead of the Junkyard Trail. Shortly after that downhill is another steep semi-technical climb and then another steep downhill, but this one is much easier.
One more climb and then you'll be bombing down a long, steep, fast downhill that drops you out at Tapia Canyon Rd. Just keep heading straight and you'll find yourself on the way up to the towers and all the singletrack.
