A simple rail trail by the river, surface is compacted gravel. This trail is historic since in the middle of the trail is the site of the big coal mine accident from years ago. Keep your eye out for the "eagle air vent" monument, that's where 30 miners escaped from.
Use the Google Map link at the left to see a map of the trailhead area.
