One of our party dithered about taking part in the climb because of a fear of heights. The steps are uneven up until the Paws, where, if you don't have a head for heights you can wait whilst others ascend the slightly rickety staircase to the top. I wore Merrell sandals with grip soles and they were great. If you are nervous about following the route, or needing a little help, you can hire a guide.
The views at the top are stunning and it is worth the climb, popping on the way back down, up to see some lusty murals. Again the cage, circular staircase, isn't for everyone.
At the top the world and his wife seem to have assembled, but it is worth it.
