The Buda Tower is at the corner of the castle. The tower can overlook the castle (you can see the Fisherman's Bastion, the church), the river and the beautiful scenery of the two banks (you can see the Parliament). You must be mentally prepared that the tower is very high, and climbing the tower is a bit tired. You can climb the tower for free if you have a Budapest Card.
