A dive into the past, into the sulphurous waters and the nature reserve of the lower Merse to experience wilderness and to relax. The ancient village of Petriolo
is located in the natural reserve of the lower Merse. Surrounded by wild but welcoming nature, it is an ideal place to relax while bathing in the natural
waterfalls with free access, or in the private spas. The remarkable places to visit are the watchtower and the ancient Church of Pope Pius II.
