Ledenika (Bulgarian: Леденика, English: icy or glacial[1]) is a cave in the Northwestern parts of the Balkan Mountains, 16 km away from the Bulgarian city of Vratsa.[2] Its entrance is approximately 830 m above sea level. The cave features an abundance of galleries and impressive karst formations including stalactites and stalagmites.[1] It was first discovered around the beginning of the 20th century and has been open to tourists since 1961.[1] Ledenika Peak on Graham Land in Antarctica is named after the cave, in recognition of its cultural importance.[3]
