Pisa is such a little town, that if you have the whole day to visit it, you can easily walk all around. Piazza dei Miracoli may be the most beautiful spot in Pisa (kids will have fun running freely around, especially if they get to climb on the top of the leaning tower), but there are many other “secret” beauties you can find. Try to walk from the leaning tower in via Santa Maria, visit for free the beautiful Botanical Garden (open in the morning), then go through the Piazza dei Cavalieri to the Borgo Stretto and Piazza Garibaldi, visit Piazza delle Vettovaglie. Walk along the river on Lungarno Mediceo, pass Museo di San Matteo and cross the bridge “Ponte della Fortezza" to see the Giardino Scotto, walk then back along the other side of the river (Lungarno Galilei & Lungarno Gambacorti) to the amazing Santa Maria della Spina church, and the San Paolo a Ripa d’Arno Church. Then Cross the ponte della Cittadella and admire the old Torre Guelfa (try to go up this tower if you have got time, you will have amazing views over Pisa and also see the Leaning tower and Piazza dei Miracoli from above).. then walk back on the Lungarno Simonelli and see the old historical buildings by the river. Yes, may be you will need to sign all these points on the map first. But the only thing is sure, Pisa has a lot to offer and even if you didn’t have time to see it all, you can always come back again.
