Hranická propast, co to je a kde to je?

Speleo-diver David Čani, a member of the Hranické Karst, will come to talk about the news, interesting things, but also the history of this unique location. From a diver's point of view, you will see and hear about the Hranická Abyss, which, with a total measured depth of 519.5 m, is the deepest abyss in the Czech Republic. At the same time, thanks to the record water depth of 450 m, it is the deepest flooded chasm in the world.
