The terrace Petroni, near the San Quirico bridge, is the gateway to the river park of the Serchio River. From here, on foot or by bicycle, you can walk or cycle along the 11 kilometre ring that, once you reach the San Pietro bridge, returns to the starting point following the banks on the right bank of the river.
The Park of the Serchio River crosses an agricultural area and is an integral part of it. Alongside the road there are crops of cereals and poplars which, arranged in a regular manner, the tall white stems and large canopies create a pleasant backdrop of light and shade.
The left side, the one closest to the city, is also the one that offers the most possibilities to stop: the skate area, the refreshment area of the "tiro della forma" an ancient game of skill in throwing cheese, the equestrian center, the Fattoira degli Albogatti with the urban gardens where you can better know the agricultural part of the silk production of Lucca, among mulberry trees and cocoons. It is here that every month in September the river festival is held with games, snacks and concerts.
On the right side you can easily access the "beach" where you can enjoy, in summer, the good coolness of the waters of the river or, in every season, go down in kayaks for long, quiet stretches of paddling, to the sea.
Every season has its beauty and colours. In spring it is the fresh green of the first buds of willow and white poplar and the coppery buds of black poplar that accompany the walk along with the flowers of chicory and mauve. In summer it is the dense foliage of poplar and willows that shade the golden yellow fields of wheat and straw. In autumn the warm colours of the leaves give a romantic air to the river on the day when Saint Frediano and the ritual blessing is celebrated. The hills are dominated by the red and yellow of the newly harvested vineyards. In winter the silvery and bare branches let your gaze reach the hills dotted with historic villas and small parish churches and up to the crests of the Apuan Alps.
