This trail is a good trail to learn on for a beginner. Nothing too difficult, the trail is good for learning some semi-technical riding. There are some tricky (again, for beginners) rock bridges to cross, but nothing overwhelming. This is one of my first mountain biking trails, so I'm obviously a little partial to it. It is one of very few trails in the Roswell area.
From downtown Roswell, take Hwy 380 east of town about 12 miles. Turn right at the Bottomless Lakes Recreation Area sign and go about five miles until the second paved road on the right. After about two hundred yards there is a gravel parking lot at the trailhead.
