Belianska Cave is the largest and only accessible high-mountain stalactite cave in the Tatra National Park — a stunning underground world hidden beneath the Belianske Tatry range. The entrance sits at 890 m above sea level on the northern slope of Kobylie Hill, inviting visitors into a labyrinth of dripstone formations, soaring domes and glittering cave pools.

Inside, the cave reveals an extraordinary variety of shapes: massive domes enlarged by rock collapse, wall-like dripstone waterfalls, pagoda-shaped stalagmites in the Palm Hall, and the quirky leaning stalagmite in the Collapsed Dome — nicknamed the 'Leaning Tower of Pisa' of the cave world. The air temperature stays between 5 and 5.8°C year-round, with humidity reaching 93–97%, so bring a warm layer regardless of the season. The cave is equally magical in midsummer heat or midwinter frost.

• Tatranská Kotlina village (parking near the cave entrance) — short walk from the car park, difficulty: easy

• Guided tours only — independent access is not permitted.
• The open tourist route is 1,135 m long with a 112 m elevation difference.
• Three protected bat species live in the cave — please do not disturb them.
• A highlight of the tour is the acoustic show in the Gallery, where a light display accompanies Pachelbel's Canon in D and other pieces to demonstrate the remarkable acoustics.
• Warm clothing is strongly recommended even in summer due to the low temperature inside.

A fascinating historical footnote: gold prospectors already knew about the cave as early as 1826 and left their names and dates written in charcoal on the walls — yet they kept their discovery secret for decades.
