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.

Rovinj is a port town on the west coast of the Istrian peninsula in Croatia. The old town, whose houses are densely packed along the water, is located on a promontory. Narrow streets lead to the hilltop Church of St. Euphemia, whose tall spire dominates the townscape and is a popular photo subject. South of the old town is Lone Bay, one of the region's numerous pebble beaches. Directly off the mainland lie the 14 islands of the Rovinj archipelago.

end of the fjord with small characteristic places. There is also a beach and an oyster farm. Pleasant until mid-morning, then literally invaded by tourists and boats.
