The Dinorwic slate quarry in North Wales, UK has a route called "snakes and ladders" which goes through Australia, the lost world and Mordor - all names given to holes in the slate quarry.
Those ladders are probably something around 100 years old and they are not be in prime condition any more but they still (most of them) have a save feel to them.
