Parco naturale di Rimigliano, Coastal nature park in San Vincenzo, Italy.

Parco naturale di Rimigliano covers about 120 hectares, excluding the public beach, along nearly six kilometres of Tuscan coast in San Vincenzo. It is densely wooded, with a continuous dune system averaging five metres high and isolated peaks above ten metres shielding the woods from sea winds. The provincial road "Della Principessa" forms its eastern edge.

The park's first protection measure dates to May 1973, when five Val di Cornia municipalities designated it an equipped territorial park. In 1997 San Vincenzo added it to Tuscany's ANPIL local protected areas. A no-building rule from the early 1970s and private Della Gherardesca ownership kept the coast intact; the municipality has since bought most of the land except Villa dei Cavalleggeri.

The park combines nature protection with public recreation, offering paths through Mediterranean vegetation where visitors encounter squirrels and wild rabbits. These wildlife encounters shape the experience while walking through the natural habitats.

Access is available through multiple entry points along a main road, with free and paid parking areas near the coastline. A network of well-marked trails allows visitors to explore the park independently.

The park's current perimeter dates to 1804-1805, when Napoleon had a coastal road built from San Vincenzo to Piombino for his sister Elisa Bonaparte, Princess of Piombino. Named "della Principessa", it cut the wooded coastal strip of Rimigliano off from the inland fields and the large Lago di Rimigliano.
