Duhlata, Natural cave in Vitosha Mountain, Bulgaria.
The cave system extends through six distinct levels with underground rivers, lakes, numerous galleries, and tunnels covering 18,200 meters in length.
The cave received official protection status as a natural landmark in 1962, marking the beginning of concentrated preservation efforts in the region.
Local residents named the cave Duhlata based on the wind sounds at its entrance, derived from the Bulgarian word 'duham' meaning to whistle.
Access to the cave requires specific permission from Vitosha Nature Park Directorate and is limited to researchers and experienced spelunkers.
The cave functions as habitat for 22 animal species, including the pseudoscorpion Neobisium kwartirnikovi, found exclusively in this location.
