The Czech Republic is a landlocked country in Central Europe and a member state of the European Union, previously known as Czechoslovakia, the country borders with Poland to the north, Germany to the northwest and southwest, Austria to the south and Slovakia to the east.  And here's the map.

The capital and largest city is Prague, which is a major tourist destination and very popular for stag and hen parties.

As this is a landlocked country, there is no marine diving, but diving takes place in lakes, quarries and the River Elbe.  There is a Padi dive centre at Slapy Dam and Lake, 40 kilometres south of Prague.
