Guided Cave Tour
The only way in is with a guide. You'll descend 88 steep steps and walk roughly 1km through three massive caverns, the largest being Tír na Nóg (61m × 49m, 18m high). The star is the Tower of Babel, a 9-metre calcite column — one of Europe's finest. Tours last 45–60 minutes at a constant 12°C, so bring a jacket. Photography is not permitted inside.
