Did a full day ride at October Mountain State Park, and it was great. If you are into serious harescrambles or enduros than this is the place for you. steep elevations, rocks, mud, roots, wide open dirt roads, beautiful scenery and a campground. I rode mostly the really gnarly trails but some locals told me there are some easier trails as well. I think some of these trails are used for an enduro thru NETRA. The trail map claims about 30 miles of trails, but there are also lots of trails not shown on the map.
