Dive-site story
Lom Kosov is a flooded multi-level limestone quarry located near Beroun in Central Bohemia. Divers navigate along stepped rock terraces, submerged trees, and occasional training platforms scattered along the floor. Below the shallow surface layer, strong thermoclines create cold conditions typical of Central European quarries.
