FAQ
How deep is the Straz pod Ralskem quarry?

The walls drop steeply from the surface, with interesting features and ledges at various depth ranges. Recreational divers typically explore the 5 to 30 meter range, while technical divers use the deeper sections for decompression training and deep air or trimix practice.
How do I get to Straz pod Ralskem quarry?
The quarry is located near the town of Straz pod Ralskem in the Liberec Region of northern Bohemia. It is approximately 90 minutes by car from Prague and about 30 minutes from Liberec. The site has parking facilities and basic amenities. Several dive centers in the region organize trips and provide air fills on-site during the diving season.
What is the visibility like at different times of year?
Visibility is best in late spring and early autumn, when algae growth is minimal and the water column is most stable. Expect 15 to 20 meters of visibility during May, June, September, and October. Mid-summer visibility can drop to 8 to 12 meters due to algae blooms in the warmer surface layers, though visibility typically improves significantly below the thermocline. Winter diving offers excellent visibility but requires serious cold-water preparation.
