Located 20 minutes east of the lake is the Canal Trail in Roanoke Rapids. The trail is 7 miles long and a nice walking or riding path. We like to park at the museum and hike west to the day use area then back for a quick 3 mile walk. Or we'll park at the aqueduct parking lot and hike east to the aqueduct (don't miss this!) and beyond.
