RAVNO: As southern Bosnia sweltered in 40 degree Celsius (104 degrees Fahrenheit), tourists have taken shelter in the constantly cool temperatures of the Unesco-listed Vjetrenica cave.
Vjetrenica, which means wind cave, is located in the south of Bosnia and Herzegovina, about 25 km (15 miles) north of the Adriatic town of Dubrovnik, where cruise liners in high season arrive daily with thousands of visitors.
Numbers allowed to visit the cave are limited because of the sensitivity of the environment. Its constant 11 degrees Celsius (52 F) temperature year-round has made it a refuge for biodiversity as well as for humans.
Visitor groups of a maximum of 80 at a time explore some of the 7.5 km labyrinth of dark corridors and spacious chambers, where legend says fairies used to dance all the way down to the Adriatic Sea.
