This dive site, Lom Velká Amerika, is a stunning flooded limestone quarry near Karlštejn, known for its dramatic high limestone walls and striking turquoise water. While visually appealing, it is officially prohibited for entry, swimming, and diving due to inherent dangers, making any attempt to explore it an unsupervised and risky endeavor. The quarry's history as a mining operation explains its unique geological formations and steep drop-offs underwater, providing a distinctive landscape.
The cool waters of Velká Amerika are home to a variety of freshwater life, including fish such as carp and perch, as well as amphibians and small invertebrates that thrive in the quarry environment. While there isn't large pelagic life typical of ocean dives, the aquatic ecosystem supports a surprising array of smaller creatures. Above the water, the steep quarry walls provide habitat for various bird species and bats.
Given the explicit prohibition on diving due to danger, there is no recommended 'best time to visit' for diving purposes, and no specific tips for safe diving can be offered. Any consideration of diving here must acknowledge the legal restrictions and significant safety risks involved. Divers are strongly advised to respect local regulations and prohibitions.
