Brijuni make a group of 14 islands and smal islands, with the total size of 736 hectares. They are proclaimed a National park in 1999, the size of which is 3000 hectares because the surrounding sea is included. They are placed along the west Istrian coast, on the opposite of the town Pula. The biggest island is Veli Brijun. On Veli Brijun there is a landscape park that is rich with Lebanon cedars, bamboos, palms and eucalyptuses. Among wild animals here abide deer, moufflons, pheasants, peacocks, and in the enclosed area there lives a diverse animal world. The one thing that has to be emphasized concerning Brijuni is their vegetative cover that is the real mediterranean community of the holm oak and macchia. The holm oak trees are up to 15 metres high and with the dimaeter of 60 centimetres, and oak and strawberry trees reach up to 12 metres and with the diameter of 30 centimetres. The coasts are low and rocky but very accessible, and in some bays there are sand and gravel sporadically. The islands in the National park are: Veli brijun, Mali Brijun, St.Marc, Gaz, Okrugljak, Supin, Supinic, Galija, Grunj, Vanga (Krasnica), Pusti (Madona), Vrsar, St.Jerolim and Kozada. Brijuni are the first class cultural historical area, because the man has lived there since the middle neolitic until today and hence left traces of his life. The Roman and Byzantine periods are very important. Brijuni are the climatic part of north Mediterranean with relatively high percent of   moisture in the air (76%). The average annual themperature is 13,9 C, and the average annual quantity of precipitation is 817 millimetres. Veliki Brijun as the biggest island of Brijuni archipelago is partly fostered into the countryside of lawns and  landscape of parks. It has valuable remains of architectural heritage and conserved vegetation. It is important to mention that the sea constitutes almost 80% of the protected area of the National park which contains almost all original elements of the Adriatic ecological system. Brijuni were the constituent part of Istrian continent about ten thousand years ago.  The islands are made of horizontal or slightly slant layers of limestone, on which there is sporadically thicker layer of brown soil or terra rossa. The stones of white colour are hard and excellent buliding material. Brijuni aquatorium is a significant fish hatchery and also a representative oasis (the sea park). The sea around the park is sometimes visited by dolphins and turtles. The underwater abounds with various species of sponges, bivalves, sea urchins, crabs and fish. The most famous fish are: lubin, orada, list, cipal,skarpina, ugor and zubatac.
