The Van Wert Rockmart Trailhead, sometimes known as Vinson Mountain Trailhead, is located in Van Wert Georgia. It is at mile marker 36.06 on the Silver Comet Trail, has a gravel parking lot, water, picnic tables, but no toilet. There's a convenience store near the trailhead on the corner of Vinson Mountain Road and Atlanta Highway. Even though the trailhead is near a main road, it is isolated and occasionally people loiter. Please use proper safety precautions when visiting this location.
Trail itself is flat and accessible; however there is a hill leading up to the trail from the parking area and wheelchair accessibility would be difficult. Likely better to use Rockmart or Coots Lake trailheads to access the Silver Comet Trail.

The Silver Comet is a paved pedestrian rail-trail located 13 miles northwest of Atlanta, Georgia. It is 61.5 miles long, free of charge, and travels through Cobb, Paulding, and Polk counties. This quiet, non-motorized trail is for walkers, hikers, bicyclists, rollerbladers, horses, dog walkers, and is mostly wheelchair accessible.

The Silver Comet starts at the Mavell Toad Trailhead in Smyrna, Georgia, and it ends at the Georgia/Alabama state line near Cedartown and the Esom Hill Trailhead. At the Georgia/Alabama state line, the Silver Comet Trail connects to the 33-mile long Chief Ladiga Trail. Both the Silver Comet and Chief Ladiga are fully paved rail-trails built on abandoned railroad lines. The combined Silver Comet and Chief Ladiga trail length is estimated to be 94.5 paved miles from Smyrna, Georgia to Anniston, Alabama.
