Jankovich Cave
Komárom-Esztergom
Jankovich Cave, located in the Gerecse Mountains within the Duna-Ipoly National Park in Hungary, is one of the country's highly protected caves. It is notable for its large, irregularly curved entrance, measuring approximately 9.5 meters wide and 8 meters high, which leads into a spacious hall about 25 meters long. The cave features an upper and lower entrance, with extensive chambers connected by a steep clay slope. Formed along a Triassic limestone fault line, the cave was shaped by thermal karst processes and is currently hydrologically inactive. Archaeological excavations have uncovered artifacts from multiple prehistoric cultures, including Paleolithic, Neolithic, and Bronze Age layers, making it a significant site for understanding early human history in the region. The cave is also a habitat for several bat species, serving as a seasonal roost. Easily accessible via marked hiking trails, Jankovich Cave is a popular destination for visitors interested in geology, archaeology, and nature. Its protected status ensures preservation of its unique geological formations and archaeological treasures.

Tip: Visitors are advised to use a light source when exploring the cave, as it is naturally dark inside. The best access is via a marked hiking trail from the resting place below the Old Stone (Öreg-kő), which is part of the National Blue Trail. No special permission is required to visit, but care should be taken to preserve the cave's delicate environment. Visiting during dry weather is recommended to avoid slippery conditions on the approach trail.

History
The cave was first mentioned in literature in 1877 and was named after Béla Jankovich following his explorations with Lajos Lóczy in the early 20th century.
Archaeological excavations conducted mainly in the early 1900s revealed layers containing artifacts from various prehistoric cultures, leading to the naming of the 'Jankovich culture' after the site.
Over time, the cave has been recognized for its geological and paleontological importance, resulting in its designation as a strictly protected natural feature within the Gerecse Landscape Protection Area.
Place Guide
Main Entrance Hall
The large irregularly curved main entrance faces east and opens into a 25-meter-long hall, initially 10-12 meters wide narrowing to 5 meters inside. The ceiling height ranges between 8 and 15 meters, featuring a 7.5-meter diameter shaft leading to the surface and two tall blind shafts at the rear.
Lower Entrance Chamber
Located about 4 meters below the main entrance, this chamber has a flat arched ceiling and measures 12 meters long, 6-10 meters wide, and 1-2 meters high. It slopes steeply downward initially, then rises slightly toward the back. This chamber lies beneath the main hall and was historically connected to the upper cave section through a now-blocked shaft filled with wedged rock blocks.
Inner Chamber
Accessible via a steep clay slope from the main hall, this nearly 10-meter-high chamber measures 6-8 meters in diameter and represents the end point of the cave's upper passages. It showcases well-preserved karst features and contributes to the cave's geological significance.
