Italy has no national law specifically permitting or banning nudism on beaches. It exists in a grey area: some beaches are "traditionally" nudist (tolerated for decades), a few have official authorization, and many wild/remote beaches have de facto nudist sections. This guide lists the ESTABLISHED spots — not places where you'll get fined.
One of the oldest established naturist beaches in Italy. Authorized. Dunes, pine forest behind. Mixed nudist/textile sections.
Long-established naturist section. 15 min walk from parking through pine forest. Adriatic side.
Remote enough that clothing is optional de facto. 60m dunes, no facilities, no one watching. The wildest beach in Italy.
Wild beach south of Lido di Dante. Established nudist community. Dunes, natural environment.
Near Fiumicino. Long-established naturist section in the nature reserve. 1h from Rome center.
Always check locally before undressing. Italian law (art. 726 Codice Penale — "atti contrari alla pubblica decenza") is vague. Established nudist beaches have community norms and are generally safe. Random beaches: risky. Local police discretion varies.
