Its length exceeds 7,200 meters, and the temperature is a constant 11 Celsius, so dress up well and take bring hiking boots and expect to climb ladders.

It was discovered in 1904 and is famous for its unique dripstones, pictured above. A 500-metre long route has lately been modernized and adjusted to meet the highest standards, we're informed.

It takes visitors to the most astonishing stone formations, drip stones, glittering calcium-crystals and prints of primeval shells. At some parts the 'perfect acoustics' of the cave can also be experienced.
