Tatár-árki Cave is one of Hungary's strictly protected caves, tucked into the steep slope of the Tatár-árok gorge in the Bükk Mountains. This is no ordinary tourist cave — it's a vital year-round refuge for bats, which is why access is completely off-limits without special permission.

The natural entrance, about 5 m high and 2 m wide, opens at 295 m above sea level, just 8 meters above the road beneath a small cliff called Kőszál. The surrounding gorge slope is rugged and wild, protected locally for its rare rocky grassland vegetation. Formed in Triassic limestone, the cave features a large fissure chamber decorated with impressive flowstone, cascading dripstone formations, and a travertine block near the entrance hinting at its past as a spring cave. Its passages stretch roughly 130-156 meters in length and reach depths of up to 45 meters.

How to get there

• From Miskolc-Bükkszentlászló, follow the Tatár-árok gorge (formerly known as Mexikó-völgy) — yellow trail marker, short approach but a steep and demanding terrain
• The cave lies at a large bend in the gorge, beneath the Kőszál rock, within a cluster of other caves scattered across this part of the Bükk Mountains

Practical information

• The cave is strictly protected — visits require permission from the Bükk National Park Directorate
• Entry is allowed only for research purposes and requires rope-climbing equipment
• A year-round visiting ban is in effect to protect resident bat colonies (including long-fingered bats and Mediterranean horseshoe bats), which stay in the cave both winter and summer
• The area around the entrance is locally protected for its botanical value

Mysterious carved rock faces and engravings have been found on the cave walls, and in 2008 bomb disposal experts removed a live World War II anti-tank grenade from inside — a small reminder of the turbulent history hidden within this rocky corner of the Bükk Mountains.
