Lom Kosov (TILOS / diving officially prohibited)
Diving is officially prohibited here, according to the dive database entry. It is a small flooded quarry about 50 x 20 m with very clear blue water, at most about 6 m deep, known for limestone and slate walls with Barrandian fossils. The entry says people dive and swim anyway, but this is without permission and without weekend supervision, so it is listed for information only.
Tiefe: 0–6 m
