From Krakow: Dive the Deepest pool in Europe

DEEPSPOT is currently the deepest multi-zone simulator of diving conditions in Europe! At 45.5 metres deep it's the place for everyone who dreams of scuba diving or freediving without stepping foot in the cold ocean. The impressive structure is fitted with a simulated "blue hole" running down to its deepest point, and even contains a small shipwreck, as well as artificial underwater caves and Mayan ruins to explore! * On this 10 hour tour including pick up and drop off, you'll be transferred in a private car and accompanied by a Master Scuba Diver Trainer. While certified divers are welcome, don't worry if you've never tried diving before, it's a great place to start. You'll even get some underwater photos to prove you did it.
