Dive-site story
Set within a dramatic, steep-sided limestone canyon often nicknamed the Czech Grand Canyon, Lom Velká Amerika is a flooded abandoned quarry. Divers navigate sheer submerged rock walls, flooded mine shafts, and relic mining equipment resting along the limestone floor. Due to strict environmental and safety regulations, diving here requires pre-arranged access permits through local speleological or diving authorities.

Seasonality
Late spring through early autumn provides warmer surface layers and the most reliable visibility, though a thick wetsuit or drysuit is necessary year-round below the thermocline.
