The Marecchia Valley is a sort of geological and geomorphological gym with everything needed to understand the genesis of the landscape, and there are many sites in the Valley that lend themselves, sometimes didactically, to the illustration of the evolutionary phases of the territory and its history. The tour is recommended for scholars and geology enthusiasts, hikers and "geocachers," but also for anyone looking for a truly unique experience. Food tastings and local wines at local farms. English-language guide.
