Want to see beautiful nature and waterfalls without any crowds? Then Una national park is the place to be! Una national park is a national park located in Bosnia and Herzegovina, just across the border from Croatia. It's just a 1.5 hour drive from Plitvice Lakes National Park so these 2 parks are ideal to combine in one trip. Una NP is a relatively new national park, it opened in 2008, and is not well known. Therefore you will have most of the places here all for yourselves! The park is quite big ( 350.0 km2) so to visit the park I would recommend visiting at least 2 days.
