Loop trek: Tosi, Vallombrosa, San Miniato in Alpe

I bought the guide "Walking in Tuscany vol. 2" and this is the first itinerary I decided to do. You start at 507 m and go above 1000 m, so it's doable in the summer period too. In general it's well signposted and runs for the most part through the wonderful, shady forest of Vallombrosa.
