Fodor's Expert Review Modra Špilja

At this popular sight hidden away on the islet of Biševo (5 nautical miles southwest of Komiža), sunlight enters through the water, reflects off the seabed, and casts the interior in a fantastic shade of blue. The Blue Cave is 24 meters (78 feet) long and 12 meters (39 feet) wide, and throughout the summer, local fishermen and tour agencies take tourists—some of whom come from Split and Hvar by speedboat—into the caverns. It can be a long wait in summer when a line of small boats is waiting to enter the cave. Ask at the marina or the tourist information office ( www.tz-komiza.hr/home-eng) to see who is offering trips. Sometimes, small boat operators will wait at the entrance of the cave for visitors arriving by sailboat and yacht (which are too large to enter the cave).
