The Val di Merse Cycling Group has also created a Gravel Grand Tour version of the Val di Merse, an invitation to slow tourism, which allows you to discover the most secret beauties of the area. The route of 217 km with 4200mt d+ with about 100km of dirt road and the asphalt part that uses a secondary road without traffic. We recommend taking the Gravel Grand Tour of the Val di Merse with a Gravel or Mountain Bike and dividing it into several stages to better savor this wonderful part of Tuscany.
