Creative workshops are organized for all ages – from the youngest to the oldest, providing an opportunity to learn new skills and express one's own creativity. The Edison Cinema will show selected film titles, and theater performances and concerts of various musical genres will fill the evening hours.

Active Spring in Nature

Karlovac, as a city on four rivers – the Korana, Kupa, Mrežnica, and Dobra – offers outstanding opportunities for outdoor activities. "Spring in Karlovac" includes organized walks with experienced Karlovac mountaineers from PD Dubovac, discovering the beauty of the surrounding hills. Adventurers can try kayak tours offered by the KAMAT Adventure agency, experiencing the city from a river perspective. For families with children, there are games and animation in the city parks. A special experience is offered by a ride on the Žitna lađa Zora grain boat on the Kupa River, an authentic wooden boat like those that once sailed this river. Partners like JU Natura Viva and Eko Pan will organize educational programs on the importance of nature conservation.

Education and Science at Your Fingertips

Spring is also a time for learning and discovery. Aquatika – freshwater aquarium Karlovac offers a fascinating insight into the richness of Croatia's river life through its modern displays. The Nikola Tesla Experience Center will bring the life and work of the great inventor closer to visitors in an interactive way. The ‘Ivan Goran Kovačić’ City Library is preparing lectures and presentations on various topics, while the Karlovac Beekeeping Society will reveal the secrets of beekeeping and the importance of bees for the ecosystem.

Gastro Experiences

An indispensable part of any experience is gastronomy. Karlovac restaurants join the event with a special themed offer of dishes inspired by spring and local ingredients. This is an excellent opportunity to taste autochthonous specialties prepared in a modern way.

Karlovac – City of Meeting Rivers and Parks

What makes Karlovac special is its unbreakable bond with rivers and greenery. The city was planned and built in the 16th century as a fortress in the shape of a six-pointed star, whose outlines are still clearly visible today, surrounded by preserved moats. But Karlovac is not just a historic fortress; it is also a city of parks. Green spaces were envisioned already during the city's planning, and this tradition of cultivating parks lives on today. The Grand Promenade, shady alleys of chestnut and linden trees, and numerous smaller parks make it a true "city within a park," ideal for relaxation and recreation.

The four rivers give the city its unique character. The Korana, which springs from the Plitvice Lakes, flows almost through the center and offers the popular Foginovo bathing place. The Kupa, interesting for its course towards the interior, was once an important trade route. The Mrežnica, with its numerous waterfalls and travertine barriers, is an emerald beauty ideal for kayaking. The Dobra, the fastest of the four rivers, becomes a paradise for rafting enthusiasts in spring. Encountering these four rivers in one city provides an incredible diversity of experiences.

Discover the Heart of Croatia in Spring

The "Spring in Karlovac" initiative is not just a collection of events; it is an invitation to explore and experience the city in its most magnificent edition. Organizers emphasize that the goal of this event, which grows year by year, is not only to attract visitors but also to provide quality content for the local population, strengthening the sense of community and pride in their city. The collaboration of a large number of stakeholders from different sectors is key to success, as it is precisely this synergy that creates a rich and layered picture of Karlovac as a destination that has much to offer.

Representatives of the involved institutions, such as the Karlovac City Museum, express satisfaction that the Tourist Board successfully connects different actors and encourages them to create new, creative content. With more than 80 different events planned during April and May, many of which are free, visitors have the opportunity to immerse themselves in the life of the city. Support from the city administration further confirms the importance of this event for the tourist and cultural development of Karlovac, inviting everyone to explore and enjoy the activities offered.
