Buckeye Trail is a 5 mile loop trail located near Lenoir, NC and is good for all skill levels. The trail is primarily used for mountain biking and is accessible year-round.
For mountain biking around here this trail system is on the mediocre side of things but a little less climb and then ride down, or vice versa, than much of what I've been finding around here. Benson Hollow is part of this trail system too. The trails are well marked and primarily used by the tenents of a nearby horseback riding campsite. The Horse club publishes an excellent map. I suspect if there's a dryer season the trails would be a pretty good cross country work out. My ride was pretty muddy and the horses exacerbate that.
