At Kotor, rent a boat to take you to Perast and ask to stop at Our Lady of the Rocks. From here it is possible to see the other islet: Sveti Dorde, but also the old town of Perast. The town is very small; however it has many churches and palazzos. #perast #montenegro #balkans #europe #boat #ourladyoftherocks #islet #island #oldtown #churches #palazzo
