About this spot
Mana Reef sits within the Kornati Islands, a limestone archipelago off the Dalmatian coast known for steep underwater geography and clear Adriatic waters. The reef spans depths from 8 to 35 metres, making it accessible to intermediate divers with basic navigation and buoyancy control. The site features rocky structures, drop-offs, and rubble zones typical of the region's karstic geology. The dive is suitable for the majority of the year, with no seasonal closures reported. Visibility varies by weather and current patterns common to the northern Adriatic, but the Kornati area generally offers decent to good water clarity during calm periods. Water temperature follows Mediterranean seasonality—warmer in summer months, cooler in winter. Marine life includes Mediterranean species such as groupers, scorpionfish, octopus, and smaller reef fish. The rocky substrate supports sponge communities and algae growth. The site is not within a Marine Protected Area, so standard Croatian dive regulations apply. Access requires a boat; most dives are organised through local operators based in nearby settlements or charter services serving the Kornati region. Mana Reef suits divers who enjoy exploring rocky reefs and walls without extreme depth or current exposure. It pairs well with other Kornati sites for multi-dive itineraries.
