Diving Brijuni National Park

Site Overview

Brijuni National Park is a archaeology dive site in Istria (West Coast), Croatia, set in the clear, fish-rich waters of the Adriatic Sea. The Brijuni islands are a protected national park with restricted diving access and a remarkable underwater archaeological heritage. Submerged Roman villa ruins, amphorae and other antiquities lie on the sandy slopes, a genuine window into Adriatic history. The reefs between the islands hold protected fish, sponges and seagrass, with a calm, sheltered character. Diving requires advance permission from the park authority and is run through licensed operators only. The combination of history and nature makes it a unique, low-impact dive. It is a highlight for divers interested in underwater archaeology and conservation. Conditions are typical of the Croatian coast: visibility generally runs from 15 to 30 metres, the current is low and the water temperature ranges between 14 and 25 degrees Celsius depending on season and depth. The marine life is classic Adriatic, centred on two-banded seabream, loggerhead sponge, common octopus, with the full community described below for those planning a dive. Because of its intermediate rating and the need for Open Water certification, Brijuni National Park is best approached with the right thermal protection and, where relevant, wreck or deep training. It is a representative example of why Croatian diving, with its wrecks, walls, caves and gorgonian forests, attracts divers who want history and Mediterranean life in equal measure.
