I recently visited this fantastic attraction with a friend who uses a wheelchair. Before we arrived we were concerned about accessibility but I am pleased to confirm that we managed the visit OK. The main entrance is higher than the exit, so, on the whole, gravity did most of the work. The walkway surface is rough in some places but it is manageable and in some places there are paths made from railway sleepers. Obviously, access to the higher levels of the theatre aren't possible, but there again I didn't want to climb up there in the heat. So overall, I would say that with a little help access for wheelchair users is possible and the sights are worth the effort.
