This is by far the best comprehensive overall view of Florence anywhere. We took a lot of photos which became our "virtual postcards" to send home to family and friends. We went in the daylight, but evening at sunset would also be beautiful. We walked, but be aware that it is a long uphill walk with a lot of stairs. Plan to bring water and take breaks if you need, but know that when you reach the top, the breathtaking view of Florence unfolding below you will make it all worth it. You can also reach the area by city bus and the hop on hop off bus. There are restaurants, souvenir stands, and stands selling gelato etc. up there as well. Florence was once a walled city and during the walk up and down from this Piazzale, we got the see part of the original wall that remains. The view is totally worth it.
