Rovinj islands
Rovinj lies on the western coast of Istria and is one of the most picturesque towns of this magical Croatian peninsula. Rovinj was not always a peninsula as it started as an island and became a peninsula in 1763. Warm, windless weather that lasts for almost a third of the year makes Rovinj a beautiful place to visit in the summer, as well as in the spring. Besides Rovinj once being an island, there are plenty of island and islets in the Rovinj archipelago. The two largest islands in the Rovinj Archipelago are St. Andrew Island – Red Island and St. Catherine. Islands vegetation is quite unique and diverse, so much so that more than 456 different plant species were counted.
