Spiaggia dei Filtri FKK lies on the coast near Duino Aurisina in the Trieste area of Friuli-Venezia Giulia. It is listed for naturist use rather than shown as an officially designated site, so expect an informal rocky shore used by adults seeking quiet naturism. The surface is exposed limestone rock and stones, with limited flat space and little natural shade. Sun exposure is high on the open rock, and shelter is limited. Access is open with no gate, ticket or fixed hours, for daylight use only. Visitors reach the water on foot along a coastal path with uneven rocky sections. Footing needs care, especially when carrying bags or wearing smooth soles. There is no dedicated beach parking, so visitors use roadside areas near the trail access and continue on foot. Public transport is limited, with the nearest stops in the Duino Aurisina area and a walk required to the shore. The site is not wheelchair accessible because of steep uneven terrain. There are no toilets, showers, lifeguard service, or food and drink services at the beach. Bring water, sun protection, swim shoes, and everything needed for a stay of a few hours, then take rubbish away. Water is clear with a rocky entry, and swim shoes are useful. Calm days are best for swimming. Morning and late afternoon offer milder sun and quieter conditions. June to September is the most practical period, while winter is unsuitable. The area is relatively sheltered but remains open to passersby on paths, so privacy is partial.
