The KRKA National Park is about 80km away and can be reached quickly via the A1 motorway.
And here aswell you're experiencing to filming locations for Winnetou movies.
Once there you must visit a paid parking slot. We recommend the parking directly at the harbor. At the parking places already available at the entrance of the Park you will save a few KN, but you may have to walk very far until you reach the harbor.
At the harbor you will find an entrance building with a large glass front. There you can pay the entrance fee for KRKA . This also includes the boat trip there and takes about 20 minutes. Little hint, if you are the very early the boarding will be very quick.
