The caves were discovered in 1938 by local teacher Vilém Greif and his helpers.
The cave system features a rare geological phenomenon called helictites, which are stalactites that grow in seemingly gravity-defying, twisted shapes.
During World War II, the caves served as a hiding place for local partisans; the village of Javoříčko above the caves was burned by Nazi forces in May 1945.
The total length of the mapped underground system exceeds 4,000 meters, though the tour routes cover a much smaller fraction.
The caves were formed primarily by the activity of the Špraněk stream, which created a multi-level labyrinth of halls and narrow corridors.
The Javoříčské caves feature one of the most extensive and complex karst cave systems in the Czech Republic, renowned for its exceptionally rich stalactite and stalagmite formations. The system consists of over four kilometers of discovered tunnels, though only a portion is accessible to the public via guided tours. Visitors navigate through large underground domes and narrow passages carved by the tectonic and erosive activity of the Špraněk stream. The site is notable for its 'Giant's Dome' and delicate 'Helictites' that grow in defying directions. The cave environment remains stable year-round, maintaining high humidity and a consistent temperature. It is located within the protected Javoříčko Karst area in the Olomouc region. The site is integrated into a landscape characterized by forested hills and limestone outcrops.
The Main Dome, where the scale of the stalactite columns and the dramatic lighting provide the best framing.
Wear warm clothing, including a jacket, as the underground temperature remains significantly lower than the surface, even in summer.
Wear sturdy, non-slip footwear as the cave pathways can be wet and slippery.
Book your tour time in advance during peak summer months to avoid waiting, as entry is only possible with a guide.
Do not attempt to visit without a pre-booked or scheduled guided group, as independent entry is not permitted.
Closed on Mondays throughout the main season; typically closed to the public entirely during the winter months.
