Bronllys castle is less than a miles walk from the front door of Three Views. It is free to visit and is worth a visit to take in the views from the top of the keep.
Although the walk to the bottom of the keep is virtual flat there are a number of steep steps in order to get into the keep itself.
It is a 11th or early 12th Century motte and 14th Century Round Stone Keep managed by Cadw.
