Look out over the Jordaan
The steps are extremely steep and there are many areas where you might bump your head. We watched a group turned away because small children are not allowed or not encouraged to climb the tower. You have a tour guide that climbs with you and provides a decent tour about the history of the church and the area. Once at the top the view is stunning and among the best in Amsterdam. A good way to look out over the Jordaan. This is not the best site or attraction in Amsterdam but it surprised me how enjoyable it was.
