It is worth the climb up the Giatto's Bell Tower in addition to the Duomo dome as the ticket that you purchase includes it. Try to go during the early morning, perhaps after your climb up the Duomo dome as the staircase may get crowded. It is a rather narrow staircase up and down as it is shared. It is several tiers of climbing up stairs to get to the top of the bell tower.
Stop at each tier and enjoy the views from them . At one point, you are able to view the top of the Duomo. The views are really great from here also, despite the barbed wire that surrounds the top deck. Take your time to enjoy the views.
