Deep freshwater quarry with easy scuba-side access.
Lom Borek is a deep freshwater quarry with a managed scuba entry, clear water, and a strong set of training-friendly facilities. The easiest plan uses the scuba side, while the swimmer side is steeper and less forgiving, so the site rewards deliberate entry choices and conservative depth planning. Because the quarry drops away quickly and stays cold below the surface layer, it is better treated as a measured freshwater dive than a casual shore dip. The attraction is the combination of easy logistics, depth, and a quarry profile that gives experienced divers room to work.

Depth range, seasonality, and planning context.
Reported Depth
0m - 34m
Depth Note
The quarry reaches about 34 m and has a steep freedive/swimmer side as well as an easier scuba-side entry.
Best Season
Late spring through early autumn is the easiest window; colder months call for drysuit or otherwise very solid insulation.
Typical Conditions
Clean freshwater quarry conditions with good visibility, cold water below the surface layer, and steep edges on the less managed side.
Hazards, restrictions, and access requirements.
Key Hazards
Safety Notes
Use the easy scuba-side entry, stay off the steep swimmer-side bank, and plan for cold water below the upper layer even in summer. The quarry drops fast once you move away from the shallow margin.
Access Restrictions
Access is fee-based and time-controlled, and the swimming side is steep enough that it is not the sensible entry for most divers.
Legal Notes
Follow the quarry access times, fee rules, and posted no-swimming zones.
Community notes to help plan your visit.
Scuba Diving
The scuba side is easy to reach, with air fills on site and enough depth to train, explore, and stretch out a quarry profile. The site is known for very clear freshwater and interesting submerged features.
Freediving
The steeper swim side and depth make it mainly a scuba site; freediving is best limited to shallow margin checks.
Snorkeling
Snorkeling is limited to the shallows; the quarry is designed around scuba access and depth training.
