Administratively speaking, the whole geographical area of the country is actually divided into different counties. There are a total of 20 counties which excludes the city of Zagreb which serves as the authoritative city bringing the count of administrative divisions to 21. But travelers to this country can learn about the major travel regions of Croatia instead.
Tourists often ask where is Croatia and which regions they can visit. The five major travel regions of the country are Istria, Kvarner, Dalmatia, Slavonia, and Central Croatia. If you want to travel to Croatia to see their business and economic district or the seat of the country, your destination should be in Central Croatia since this is the region where the capital city of Zagreb is located.
For those tourists who are more into the historical sites and attractions, the region of Dalmatia would be perfect since the cities of Dubrovnik and Zadar are found there. These two cities have very rich histories and Dubrovnik is even listed as a World Heritage Site by UNESCO. Since biodiversity is an important aspect in Croatia especially in tourism, tourists and visitors can go to Kvarner where the sea meets the highlands. Slavonia is also a good area where lush forests can be found.
