The boat also makes a trip around the coastline and at the same time passes separately through each cave. The sight that visitors can admire when they pass through the caves is fantastic. The sunlight reflects on the rocks and the waters take a particular green color. The boat makes a short stop inside the caves so many visitors have the chance to swim around there. Usually after the caves the boat trip ends in the exotic beach of Rovinia where there anyone can stay until late and come back with the next route. The cost of the boat trip is about 10 to 15 Euros per person and depends on trip that you will choose.
