Jaskinia Mylna, Cave system in Kościeliska Valley, Poland.
Jaskinia Mylna is a cave system in the Kościeliska Valley in Poland with two main entrances at 1098 and 1084 meters elevation. The system extends through 1630 meters of passages and forms a natural underground network of several interconnected chambers.
Jan Gwalbert Pawlikowski first explored the cave in 1885 and named sections including the White Street, the Great Chamber, and the Choirs. His expedition laid the groundwork for the scientific mapping of the underground labyrinth.
Local tales mention that the cave provided shelter to Janosik, a mountain outlaw from the early 18th century who became a folk hero. This mountain outlaw still shapes regional storytelling and adds a romantic layer to the site in local oral tradition.
Visitors need personal lighting equipment to navigate the 300-meter tourist route, as the cave maintains temperatures around 5 degrees Celsius in summer. Warm clothing is recommended, and access requires basic surefootedness on uneven ground.
The cave features three natural windows that offer views of the Bystra and Błyszcz mountains. These openings allow daylight into certain sections and create a rare connection between the underground world and the surrounding mountain landscape.
