The Brijuni is a small archipelago comprised of fourteen islands and islets, and these islands are situated along the western coast of the peninsula Istria. The islands are separated from the Istrian mainland by the Fažana Channel which is 3 kilometers wide. This former private resort of Josip Broz Tito lies north of Pula and in 1983 it acquired the status of the national park and became open for the tourists. The most indented islands are Veliki Brijun (25.9km) and Mali Brijun (8.3km), which are also the only ones, on which the visitors are allowed. The shores are mostly low and rocky but easily accessible. The horizontal stratification of the rocks is the main reason for that. The National Park of Brijuni includes the following islands: Veliki Brijun, Mali Brijun, St. Mark, Gaz, Okrugljak, Supin, Supinić, Galija, Grunj, Vanga (Krasnica), Pusti (Madona), Vrsar, St. Jerome and Kozada. (Krasnica), Pusti (Madona), Vrsar, Sv.Jerolim and Kozada. The islands are made of horizontal or slightly inclined layers of limestone from the Cretaceous. The stone that belongs to that formation is white in colour, easily breakable, of marble structure and is abundant in clay and flint. Therefore it is very solid and is an excellent building material. Roman builders appreciated the listed qualities of these stones and it was used to build many towns on the Adriatic.

The islands are characterized by a Mediterranean climate - which is a synonym for mild. There is plenty of sun and warmth here, humidity is the reason for rich vegetation. The average temperature in winter period is 6,3°C and in summer 22,2°C. The sea temperature in summer is from 22 to 25°C. The main characteristic of the Brijuni archipelago is the extraordinary biological diversity. This is due to the geographic position of the islands, but also to its geological and geomorphological characteristics. Another characteristic that makes Brijuni even more valuable in relation to other areas of this climate is its vegetation. The majority of the flora on the archipelago of Brijuni has the typical Mediterranean characteristics. Besides the domestic (autochthonous) genuses, the plant inventory of the parks is also made up of imported (allochthonous) species:: the stone pine, the Aleppo pine, the west-Mediterranean maritime pine, the brucian pine, the black pine, the Atlantic, Himalayan and Lebanese cedars, the Greek and Spanish firs, the sequoia, the cypress, the eucalyptus and others. In 1893 on the island lived the European hare (Lepus europaeus sp.) and between 1902 and 1908 the Aksis deer (Aksis aksis), the fallow deer (Dama dama) and the mouflons (Ovis musimon) were imported, so their descendants still adorn the forests, parks and glades of Brijuni and are part of its identity. The autochthonous birds are quite well represented. Some of the smaller islands are excellent habitats where gulls and sea swallows nest, as well as some rare genuses of cormorants. Brijuni are also important seasonal habitats of northern bird species and the most interesting is the locality of Saline. That is a very damp area with three marshy lakes of 8 acres of fenced area with the aim of forming an ornithological reservation. The ethno park is an area within the Safari park presenting a typical Istrian homestead with its autochthonous animal species. Istrian ox (Boškarin), Istrian sheep (Istrian "Pramenka"), donkeys and goats. It is intended both as a habitat and presentation of domestic animals of Istria. There you can also see structures suitable for such farm animals, such as the Istrian open "tetoja" (covered area with feeder for farm animals). On the northern edge of Veli Brijun, in an enclosed area stretching over 9 hectares, lies the safari park that was formed in 1978. The park is the habitat of many exotic plant eaters: Indian elephants Sony and Lanka, llamas - South American camels which according to the Indian legend were domesticated in the very beginnings of human existence, zebras, nilgais and kob antelopes, Somalian sheep, Indian holy cows and autochthonous donkeys.
