Kolpa River is the natural border between Croatia and Slovenia, and remains virtually untouched.
Kolpa River is one of Slovenia’s hidden gems. Slovenia is known for its amazing natural beauty, and Kolpa River tends to go under the radar. The river is beautiful and untouched, and the unpolluted waters make it a great place for a swim in summertime.
Kolpa River is 297 kilometers long, which makes for drastic changes in landscape when exploring. In some areas, you’ll find mountainous regions, and the next you’ll be in flat countrysides. The waters are calm, making it safe to discover the river by canoeing. Other options include hiking and biking.
