Although relatively small and lesser-known to the general public, the Cvrcka River, located between Kneževo and Kotor Varoš, is considered a natural gem with substantial tourism potential.
The largest left tributary of the Vrbanja River, Cvrcka originates on the northeastern slopes of Čemernica, on the watershed between the Jakotina River and streams that flow into the Ugar.
Exploring the breathtaking Cvrcka Canyon requires between 6 to 10 hours. With its numerous waterfalls, cascades, steep cliffs, and natural water slides, this location poses a real challenge for canyoning enthusiasts.
The Cvrcka Valley is also highly appealing for hiking, as a footpath runs the length of the canyon, offering picturesque landscapes and authentic watermills along the way. The river joins the Vrbanja at the villages of Vrbanjci and Večići in the Kotor Varoš region.
Cvrcka itself forms from two headwaters—Međurača, with a source at around 1,100 meters above sea level, and Vukača, sourced at around 850 meters above sea level.
After merging with its only tributary, Bukovica, Cvrcka flows into a deep and steep canyon with a western wall that is largely inaccessible. The canyon reaches depths of up to 400 meters in some places relative to the surrounding plateau.
Within the canyon, a series of cascading pools adds to the area's allure, and near the canyon’s end below the village of Hrastik, lies the spectacular Vilenjska Vrela, or Fairy Springs—a powerful source on the right cliff where water sprays down in misty streams. In the 1960s, Cvrcka was home to around 30 watermills, highlighting its historical importance to the local community.
