The long stage 29 which links the city of bread, Altopascio, to the city of white truffle, San Miniato, winds mainly on flat, enclosing, with its variant crossing the area of Ponte Buggianese, firstly the Sibolla Lake and then the largest internal wetland area in Italy, Padule di Fucecchio.

The alternative itinerary, characterized by evocative marsh environments where numerous bird species live and radiated with canals that will be skirted along the way, has been named “water variant” for good reason. Departing from Altopascio, the variant, after crossing the marsh, joins the official route of stage 29 in Ponte a Cappiano, an ancient Medicean bridge that today houses a hostel.

It is possible to make provision of water in Chimenti, Galleno, Ponte a Cappiano and Fucecchio.
