In the heart of the Cilento and Vallo di Diano National Park, Prignano Cilento stands out for the presence of the Oasi Fiume Alento (Alento River Oasis), a naturalistic gem that enriches its territory.
The Oasis, located within a 3,024-hectare Site of Community Importance (SCI), encompasses a large portion of the Alento River and is a highly valuable natural park, capable of offering a wide range of tourist services. At the center of the Oasis is an earth dam which, by barring the river's course, created an artificial lake of just under 2 square kilometers. Along the right bank of the river, an area rich in ecologically significant small lakes has developed, whose primary purpose is the conservation and protection of biodiversity. The integrity of this natural habitat, which has attracted families, schools, and outdoor sports enthusiasts for years, represents one of the main attractions for those wishing to immerse themselves in the pristine beauty of the Cilento nature.
