The lake is a part of Circeo National Park, consisting of yet other lakes along the coast to the south, a forest, and the Circeo mountain. All are worth a visit, depending on season.
On this place some nice birds you can see are Black-necked Grebe, Gull-billed Tern, Booted Eagle, Audouin's Gull, Glossy Ibis and European Marsh Harrier.
It is possible to get to the eastern side from Strada Litoranea. Park along the road, just before the bridge over the dyke. Here there are paths to the hides. It is also possible to access the lake from the west. There is a parking place just north of the lake, along the Via Del Lido. From here is possible to walk out along the northern side of the lake.
