Jim,
we actually discussed it with the Ranger there and she suggested that my knee wouldn't be able to handle the stairs and certainly not the ladders. But still, the entire area is just full of things to see and stuff to learn. We had a great time. And we did go through the ruins at the Anastazi Museum in Dolores -- I even climbed around a bit inside by hoisting myself onto one of the ledges. Fascinating stuff.
