Karlovac is a city in Croatia, 55 kilometres away from the capital Zagreb. Unlike busy Zagreb, Karlovac is a quiet area at the junction of mountainous and lowland Croatia. It is surrounded by four rivers: Kupa, Mrežnica, Korana and Dobra. Karlovac is an important traffic centre both today and throughout history. The historic roads of Louisiana, Carolina and Josephine have always connected the city of Karlovac with important economic centres of this part of Europe as well as ports on the Adriatic. The city was founded in 1579, and its role as a fortress on the border of the Habsburg monarchy has been important throughout history. Thus it was built according to the ideas of the Renaissance and the architects of that time - it has the correct geometric shape of a six-pointed star. Green valleys of four rivers, centuries-old parks and promenades, bicycle and hiking trails - all this ranks Karlovac among the most beautiful cities in Croatia that offer the perfect scene for an active vacation. The most famous Karlovac company is Karlovačka pivovara, and the Karlovac Beer Days event with an increasing number of visitors. If you rent accommodation in Karlovac, you will have the opportunity to enjoy numerous cultural and recreational facilities, and the only freshwater aquarium in Croatia Aquatica, which has over five thousand fish individuals.
