Karlovac, city of four rivers: your base in inland Croatia

    Four rivers, one special town

    It’s not for nothing that Karlovac is known as the town of four rivers. The Korana, the Mrežnica, the Kupa and the Dobra all converge here, giving the town an atmosphere you won’t find anywhere else. Strolling along the banks, swimming in the clear, flowing water or simply sitting and watching the water find its way – it’s all possible, right near the city centre.

    As well as its rivers, Karlovac also has an interesting historic centre with Renaissance and Baroque influences. The town was founded in the sixteenth century as a military fortress, and this is still evident in the star-shaped layout of the old town. Strolling through those historic streets and squares gives you a very different impression of Croatia from the bustling coastal resorts.

    And then there’s Plitvice National Park, about 80 kilometres from Karlovac. This UNESCO World Heritage Site, with its system of turquoise lakes and waterfalls, is an absolute must-see. Head there early in the morning to experience it at its most peaceful. Zagreb, the bustling capital with fascinating museums, art galleries and lively terraces, is 80 kilometres away.

    Rafting, canoeing and swimming in the great outdoors

    The rivers around Karlovac aren’t just beautiful to look at. The Mrežnica offers excellent opportunities for rafting, whilst the Korana is perfect for canoeing. Along the way, you’ll pass waterfalls such as those at Lipa and Grdunac, where you can also go for a swim. KAMAT Adventure organises guided trips on these rivers, so you can get out on the water even without your own kit.

    This is the Croatian countryside at its best: green, peaceful and full of activity all at once.

    Accommodation near Karlovac

    If you want to explore all this, you’ll need a good base. We’ve found one that really appeals to us: Camping Heart of Nature, a farm stay in the rolling, wooded landscape of the Croatian countryside, about 20 kilometres from Karlovac.

    What makes this campsite special is the combination of tranquillity, character and activities. The swimming pool has a retractable roof, so you can still go for a swim even in changeable weather. The Petrova klet restaurant serves authentic local dishes, its own wine and prosciutto daily from 12 noon to 10 pm. And in the campsite shop, you’ll find local organic produce: cheese, honey, sausages and wine. Canoeing, rafting and fishing on the nearby rivers Korana, Kupa, Mrežnica and Dobra can all be easily arranged from the campsite, as can bike hire for exploring the woods.

    When to go?

    The climate in the Croatian hinterland is pleasant from June to September. In July and August, daytime temperatures rise to an average of 28 degrees, whilst nights remain around 16 degrees. June and September are the quieter months, with average daytime temperatures of 25 and 23 degrees respectively, ideal if you prefer to avoid the crowds. Camping Heart of Nature is open from June to September.

    I’d say: leave the coast behind for a while and discover what the Croatian hinterland has to offer. You won’t regret it.

    Good restaurant. If you are a bigger group, I recommend to order food in advance. Also if you wish to have a bit more complicated dish like for example meat under the bell, order it in advance. The same complex also offers glamping, rooms, camping spots, soccer field, swimmingpool...
