Principina a Mare is a seaside resort located on the northern border of the Maremma Park. During winter, it is almost completely uninhabited, while in summer, particularly in July and August, it becomes a very busy destination. It lies within the Granducale Pine Forest in Grosseto and features low buildings and single dwellings surrounded by greenery.
The resort is popular thanks to its large stretches of free beach, shallow waters and sloping seabed, making it suitable for families with children.
Its closeness to the Maremma Park and other natural areas, like the Diaccia Botrona Nature Reserve and the WWF Oasis of San Felice, together with the bike paths connecting it to other coastal resorts and to the city of Grosseto, help make it a destination suitable for those seeking vacations in contact with nature and quiet beaches.
