On March 21 and 22, 2026, the first weekend in spring, the Garden of Ninfa will officially reopen to the public. The Fondazione Caetani has published on the website Oasi Naturale del Giardino di Ninfa the 2026 calendar of visits, to be booked exclusively online. The openings are scheduled on weekends and holidays, from March to November, and the evening ones from Friday to Sunday with themed tours at sunset from July 3 to August 30.
It will be possible to admire not only the enchanting Garden of Ninfa, but also other Caetani sites. Numerous events will take place in Pantanello Park, the approximately one-hundred-hectare area adjacent to the Gardens, where the wetlands of the ancient Pontine Plain have been splendidly recreated. Also not to be missed is the Caetani Castle in the heart of the medieval village of Sermoneta.
