Red Lizard is a very steep and rocky trail that starts from a neighborhood off of Dug Hill Road and runs to the Warpath Ridge
To access the trail, park on Elk Medows Drive and make your way across Williams and Broad Drive through the ditch to the trailhead. The start is not marked but is easily found through the ditch directly across from Elk Medows Drive.
Even though this is a short trail, it's extremely difficult and rocky the entire way. It can be difficult to follow at times, but it features red lizard blazes spray painted along the trail to help you navigate the rocky path.
When you reach the end, you may not know you're actually finished since nothing is marked. You'll probably have a pretty good inkling that you're close when you start to see the opening to the power line cut.
I have written an article
