Pirate Cave Bar at Lim Bay
Highlight • Cafe
One of these stories is often told on the Croatian Adriatic. On the northern cliffs of the Limski Canal, where the sea pushes inland in a narrow gorge between Poreč and Rovinji, there are caves that were a popular hiding place for pirates in past centuries. A cave that was already a filming location for the Winnetou films and the Hollywood film "The Vikings" with Kirk Douglas and Tony Curtis and is therefore particularly exploited by tourists is said to have also served as a refuge for Henry Morgan.

A very beautiful and interesting highlight. Not very crowded. Unfortunately, there are quite a few broken pieces here. A flashlight is a good idea.

A very attractive path between the rocks. If you continue, you'll be rewarded with a magnificent view. Unfortunately, there are a lot of broken glass here. Be careful with dogs!

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.

The walk along the stream has its own idyllic charm. What's more, the hiking here is quite good; there are worse paths...

Beautiful little cave. We were alone in there. The guide was allowed to unlock it and turn on all the lights. We didn't want to at first, but it's good that we did.
