Do you want to go to an attraction that makes your knees buckle and is way too cramped? Than St Canice’s round tower is for you! It costs €3 to go up and can only hold 12 people at a time. There is a commentary as you ascend the tower, with history and quippy comments. It quite funny!
Be warned this is definitely not something everyone can do. The stairs are steep and it’s very much single file, you have to time it right so there aren’t lots of people on the stairs as there isn’t much room on each floor.
The views from the top are worth it though, there is a 360 degree view of Kilkenny and if you go on a sunny day it will be beautiful! There is a combined ticket with the cathedral for €6. There’s not much else to say on this but I do think you should try it at least once. It’s fun when you at safely outside on some flat ground. Give it a try!
