The Czech Republic is a beautiful country full of rolling meadows, glorious mountaintops, whimsical castles and picturesque villages. What more could one need? The sea! In a landlocked country one can sometimes feel a bit trapped or claustrophobic, and you could miss the relaxation and mental clarity that comes along with swimming or floating in the sea or a large body of water. Prague has the curving Vltava River, but like all rivers by large cities, it is not suitable for swimming. Prague offers good indoor-outdoor swimming pools, a few aqua parks and manmade reservoirs for swimming.
