The source of Kupa is a small karst lake of turquoise green colour near the village of Razloge in Gorski Kotar. Downstream, Kupa is a fast river, but later it loses its speed and slows into a calm river, with numerous weirs that were once used for powering watermills and flour mills. It runs wild in its upper part, which is why boat rides here offer a true adrenaline experience, and its clean and crystal-clear waters are nice for swimming during the summer.

In its upper reaches, Kupa makes its way through a wooded canyon. The source of the river is one of the strongest, widest and deepest springs in Croatia.

As the second largest river of Gorski Kotar, Dobra River forms east of Skrad, from a number of smaller headstreams at Bukov Vrh, joined by Kamačnik near Vrbovsko. Dobra is a subterranean river, and its valley consists of broadenings and gorges. Near Ogulin, its flow disappears in the remarkable Đulin Ponor, and then emerges again some dozen kilometres downstream in the form of a powerful spring (Gojačka Dobra). It features two watermills still in operation and two hydroelectric power plants, and abounds in various species of fish.

Čabranka, the left tributary of Kupa, measures only 15 km in length and emerges from the cracks of the steep rocks of Veliki Obrh (546 m), located about a fifteen-minute walk from the centre of Čabar. Throughout its entire course it acts as a border river between Slovenia and Croatia.

It owes its stunning appearance, right from its source, to its numerous waterfalls and rapids. It was recognised as a protected area in 1961.

The source of the underground river Gerovčica emerges beneath a 300 m tall cliff. It never dries up, and in the summer, it doesn’t flow in the Gerovo valley. The river’s course is marked by scenic rapids and beautiful natural landscapes.

A reservoir up to 40 metres deep in places. It stretches up to the foot of Risnjak, creating a unique visual postcard. It was constructed in 1954 when a dam was built to stop the flow of the river Lokvarka. Lake Lokve is a traditional gathering place for hikers and ramblers, as well as cyclists. In addition to walks along the lake, it is also great for swimming in the summer, or fishing throughout the year. Some of the world’s largest trout were caught here!

The reservoir was constructed in 1952 when a dam was built on the river Ličanka, near the centre of Fužine. The lake is 2 to 7 metres deep. A scenic, 7 km long hiking trail for pedestrians and cyclists wraps around Bajer. You can also enjoy the tourist train or horse-drawn carriage, or the tourist boat ride on the lake.

The largest reservoir in the Fužine area. It was built in 1988 and has a maximum depth of 18 metres, and its surface area and water amount considerably exceed that of Bajer Lake.

It is suitable for swimming in the summer months, as the water temperature can reach more than 23 °C. It is also the venue for annual competitions in underwater orienteering.

This tiny pearl is located along the “old” Lujzijana road in Moravice, a well-known railway hub. The lake is located 8 km from Vrbovsko and boasts refreshing beauty. The source of Čogrljevo Lake is made up of five smaller sources, flowing into the lake. The existing waterfall of Vede forms a reservoir once used for powering a small sawmill and flour mill. The trail around the lake located on the edge of a fragrant coniferous forest also offers the possibility of touring the springs. If you are patient enough and have a keen eye, you will see the most beautiful resident of the lake – the lake trout.

The youngest and smallest lake in the Fužine area. It is located at the foot of the slopes of Bitoraj, between Fužine and Lič.

It is a popular excursion spot and offers a large area for picnic.
