About a hundred meters below the largest and best-preserved medieval castle in Istria, you'll find the Pazinčica, Istria's largest underground river. The river's gorge represents the most significant example of karst evolution in Istria and its surrounding area. Along its course, the river forms numerous small waterfalls, the most interesting of which are the Pazinski and Zarečki Krov. The Pazinčica River resurfaces as the Raša River.
