Szemlő-hegy Cave

This beautiful cave, about 1km southeast of Pál-völgy Cave and Mátyáshegy Cave caves, is the most accessible of the three. The temperature at Szemlőhegy is 12°C and the cave has no stalactites or stalagmites; instead, it's notable for its peculiar "grape" (some say "popcorn") formations. The tour lasts about 45 minutes. The lower part of the cave has been used as a respiratory sanatorium due the exceptional quality of its air.
