Amatérská jeskyně (CSAK KUTATÁS / research only)
Diving is prohibited for the public: the cave is closed and explored only by authorised speleologists. Amatérská jeskyně in the Moravian Karst PLA is nearly 45 km long, the longest cave system in Central Europe. Cavers began diving the siphon at the end of the Flood Passage in August 1969 and found the Nová Amatérská jeskyně beyond it. A roughly 100 m siphon from cave C13 was first passed in 1983 and the last Sloup corridor siphon in 2005. Coordinates are the position given on Czech Wikipedia.
