A compact freshwater quarry dive with a few man-made features and seasonal water
Lom Hříměždice is a small flooded granite quarry in Central Bohemia that attracts divers looking for an easy, sheltered freshwater dive with a bit of character. The underwater terrain is compact and simple to navigate, with a few man-made points of interest to visit such as a mine cart and a short crawl-through tube, plus seasonal water lilies. Plan around heavy summer recreational use, as the site is commonly treated as a swimming spot and diving is typically recommended outside the main summer season. Facilities are minimal, so arrive self-sufficient and use the on-site shelter only for basic kitting up.
