Monte Serra is the mountain sung by Dante “… so the Pisans can’t see Lucca …”. With its 800 meters, it is a mountain of modest size but not to be underestimated. It has three climbs on three different sides and each has its good difficulties. A ride on its summit starting from Viareggio presents a long approach ride on the plain, and then leads us to its top along one of these three climbs, two of which are beautiful and in the shade, perfect for summer days, while the third from Calci , challenging at the beginning, takes place in a landscape that has become lunar after a fire devastated its lush forests in 2017. All these three roads are to be traveled at least once if we love cycling. The 360 ° view rewards fatigue. Pisa is under them close at hand.
