Nope the winch would pull it into that big rock, we tried it. I climbed way up the hillside, but all the rocks I could hook to, to get a good pull, looked like they would tumble down the hill. We actually winched several rocks down to try and make it do able. Screwed with it for atleast an hour and a half with it. Tried stacking rocks, just thew climb was sandy and couldn't get the rocks to stay put, would spit right out.
