From the main road heading to Rijeka or Karlovac, turn into the village of Klanac at the restaurant Mirni Kut.
Turn right and drive down the hill until you reach the river. The road is not visible in google maps but has lately been paved and widened so no worries!
There are some unorganized parking places. Avoid weekends.
Definitely one of the loveliest a beautiful spots on river Kupa. In the early days, the Kupa river had many watermills. Most of them have withered and nowadays only the remains can be found. Nevertheless, the artificial waterfall at Klanac is very beautiful and when the water is low you can walk to the other side of the river and visit the little hamlet of Damelj, Slovenia.
The village is an ideal setting for morning photography. There is not just the waterfall that is very photogenic. About 200 meters upstream you can spot a very nice old watermill that is still in good shape. The village next to Klanac is Damalj (see picture 2). The church and the old houses make it a very picturesque place. The Kupa itself is sleepy, dreamy and fairytale-like at this location.
Take a walk:
You can consider a short walk from the Kupa river at Klanac to the next village of Damalj. It is very easy just walk through the fields. There is a pathway that leads you to the village.
The second option is just to follow the course of the river till the next waterfall and even further. The road is narrow and unpaved but easy to walk.
Take a break:
There are picnic benches at the riverside and a grill.
Up in the village is the traditional restaurant of Mirni Kut
The next village of Severin na Kupi has a small grocery store and two coffee bars and a gas station. This village also hosts one of the many Frankopan castles in Croatia.
Klanac is famous for the morning mist. In fact, every time I come there during late Summer, Autumn, Winter and early Spring there is morning mist. The mist adds so much more atmosphere to a picture. Sunlight comes into the Kupa valley about an hour after sunrise. Even though the Autumn colours are much more attractive this location is an all year round photo hot spot.
Watch the local weather report (I can highly recommend the YR app) for weather circumstances.
