Feniglia is a sand isthmus about 6-km long that connects the hill in Ansedonia with Monte Argentario. Easy to reach by taking the E80 road to Ansedonia and then the local road, it is a nature reserve that can only be reached on foot or by bicycle (rental available on site) along an unpaved road, arriving at the beach by following narrow tracks crossing the Mediterranean scrub. The beach is free of charge and there are no food facilities.
