Yes you can ride there. There is a couple sled cabins on the back side and there used to be some good climbing and powder fields back there but I think they have a lift or 2 back there now also. You can access Greystokes from there or drive back down a bit to the 201 FSR and take that back in behind between the ski hill and Stokes. Find yourself the sled map for Greystokes which has references to intersection signs, and a GPS makes things simple. Or you could just call the club and line up a guide!
