I caught some tourists as they went on down the stairs, and there were stairs cut into the wall. If you look close to the right of stairs, there is a handrail visible which shows the cant of the climb down. When I climbed up, I lost my waterbottle from my backpack. It bounced down about two bounces and a Japanese woman caught it and gave it back to me. We had to applaud the catch, but gravity had that plastic bottle bouncing high!
