Flooded quarry in Blansko

The flooded quarry in Blansko is a former extraction site that has filled with water, featuring steep stone walls surrounding a deep body reaching about 60 feet (18 meters) deep. The geological layers of rock are clearly visible through the transparent water, creating distinctive striations across the walls.

The quarry began as an industrial stone extraction site and was gradually flooded by groundwater over time. The abandoned mining operations transformed it into a natural landmark that now serves a different purpose than its original use.

The flooded quarry serves as a gathering spot for local people, especially during summer when swimmers and outdoor enthusiasts come to enjoy the water. Over time it has become a social destination where the community spends leisure time.

There are no supervised swimming areas, lifeguards, or safety equipment at this location, so visitors should take their own precautions. A railroad runs very close by and may affect your visit timing or experience.

The exceptionally clear water allows visitors to see the rock layers in detail, making it an unusual place to observe geology firsthand. This transparency is rare at former extraction sites and creates a memorable viewing experience.
