Rosolina lies between the gardens and the unique and unrepeatable environment of the Caleri Lagoon and the fishing valleys, to the north of the Po Delta bounded to the north by the Adige river, to the south by the river artery formed by the Po di Levante, to the east by the waters of the Adriatic Sea. Here, in the 50s of the last century, was born the tourist resort of Rosolina Mare: a natural landscape of rare beauty overlooking a wide coastline. A real paradise for a seaside holiday, able to offer tourists different possibilities such as the itinerary inside the suggestive Botanical Garden of Porto Caleri and the boat excursions in the homonymous lagoon, famous for its mussel and aquaculture areas. Rosolina is in the heart of the Veneto Regional Park of the Po Delta, an area of international importance and one of the most important naturalistic parks in Italy and Europe, included in the UNESCO Biosphere Reserve in 2015. A rich and varied universe, important for its biodiversity, which offers the most sensitive visitor, those who love to immerse themselves in nature, listen to its rhythms, smell its scents, a truly fascinating, exciting and unique experience.
