This large protected area hosts one of the rarest ecosystems in Italy: the swamplands give life to innumerable plant and animal species which are able to live only in this habitat. San Rossore is also famous for the Presidential Estate, a significant historical and cultural testimonial of the Grand duchy and the current Republic. We will rent bicycles and during our excursion one of the park guides will accompany us and will explain the nature around us. Before returning, a stop at the most famous tower in the world – the Leaning Tower of Pisa – is a must.
