Pianosa Island (Long. 10 ° 04'44 "E and Lat. 42 ° 35'07" N) is the fifth largest of the seven islands of the Tuscan Archipelago National Park. Located just 10 miles West of the Elba Island, Pianosa has an area of ​​10.3 km 2 and a coastal perimeter of about 18 km. Formerly called “Planasia”, the island bears this name because it is very flat, with the maximum elevation of 29 m and an average
altitude of 15-20 m above sea level.
The island is made up of limestone sediments on a clay base. The climate of Pianosa is particularly regulated by its morphology, in fact the flat shape does not allow the condensation of humid air masses with significantly lower rainfall compared to the other islands of the National Park.
