This 1.8 mile one way rail trail is an easy walk through the woods and features two old bridges, an old mine entrance, and a waterfall.
You can start walking on this well-graded rail trail either from Ansted or down by the New River at the Hawk's Nest Nature Center. If you start from the top you will lose a couple hundred feet in elevation and have to walk back up to your car (it is an easy walk though). Bikes are also allowed on this trail.
It is easy to follow this trail, and you will cross two old train bridges, and old mill site, two waterfalls on Mill Creek, and an old mine entrance along the way. For such a short trail, there is a lot of scenery and interesting features to see.
The trail won't take long to complete since it is mostly flat, so once finished you could try some of the other trails in Hawk's Nest State Park or visit the Hawk's Nest Overlook.
