I advise you to start your visit from the Rione Aia Piccola residential area with "only" 400 trulli. This area will gently take you to reach the most beautiful attractions of Alberobello, concentrated in the Rione Monti. The Aia Piccola district (UNESCO protected heritage), is used as a residential center: no commercial activity can be open and, for this reason, you will find yourself walking in a very authentic area.
