There are more than 400 stairs and only 25 people can go up every half hour. So you have to take your time and be in good shape as the stairs are narrow and take some effort. But the view on the top is breathtaking. Enjoy

The famous tower of Siena, which worth to climbed up, if you aren't claustrophobic. Because the stairs are quite narrow. But amazing strong tower, able to 'carry' lots of people (tourists) ups & downs, especially during peak summer time. The view from the top is quite breath taking. Apparently Tower of Mangia inspired the design of the clock tower 'Old Joe' at University of Birmingham, UK.

A nice high stair climb up the tower for a beautiful view of the plazza Old building and tower in the Plazza del Campo. I cannot remember the price to climb to the top I believe it was on the steep end for what you get. You don't need to worry about the stairs if you are afraid of heights but it might bother you if you are claustrophobic as it's pretty narrow going up / down and can be even tighter if someone is coming the other way. The tower provides a great view of the Plazza del Campo and the surrounding Sienna area.

€10 is a bit much considering the arrangement: narrow stairways mean one-way access at any time. You also have to wait for the light signal at the bottom of the tower to go green ("Avanti"). That said, the view from the top is spectacular from all four sides so be sure to bring a camera. Don't go if you're claustrophobic or suffer from vertigo.

The view at the top is amazing. Stairs are narrow but those with a fear of height shouldnt worry. Only downside is all the staff were super unfriendly however you dont go there for good service...
