We'll be visiting the end of June, and I want to climb St. Peter's dome and the tower of Pisa. We're older, so it won't be as easy. I'm "training" for it, but I'm not sure my sister-in-law will be able to make it up and back.
Can climbers "change" their mind half way up and turn around? Or are the narrow steps one-way only, with no way to get to the Down steps while we're enroute?
Thanks for answering this rather dumb question, but it would help if we knew. Thanks.
