if you have high clearance 4 wheel drive just keep driving past the campsites and youll find something, otherwise there isnt much around that I know of. maybe the next road into the forest service land to the south
+1 for high clearance vehicle to drive past the campground/recreation area. otherwise check out campground(s) at the southern end of the Nebo loop or in-between Nephi and Fountain Green. just please don't create your own/new campsite along the shoulder of the road. if you would like specific directions PM me.
