Trekking a Siena e Toscana con 43° Parallelo

Hiking to Canale del Granduca

This tunnel was built at the end of 1700, to drain a swamp, today called Pian del Lago. This bold and visionary work is still doing well its job today offering us the opportunity to walk inside it for the entire length. Along its about 2 kilometers we will be able to observe interesting geological phenomena and sometimes curious hosts. Combined with the visit to the hermitages of Lecceto and San Leonardo al Lago the day will be enriched with historical and architectural interest, along an easy loop.
History, nature, and adventure few minutes away from Siena!
Just the visit of the tunnel will take half day. With the hermitages you will need a pleasant entire day.
Basic trekking equipment, headlamp. At the car dry socks and shoes. In the slippery parts inside the tunnel, hiking poles could be useful for those who are accustomed to.
