Slovak Republic (map) is a landlocked country in Central Europe. The capital and largest city is Bratislava, and the second-largest city is Košice. The main reasons to visit Slovakia are its natural beauty, vivid history and great opportunities for relaxation (and due to the small size of the country, it is quite easy to combine all three).
The Slovak landscape is noted primarily for its mountainous nature, with the *Carpathian Mountains extending across most of the northern half of the country. To the north, close to the Polish border, are the *High Tatras which are a popular hiking and skiing destination and home to many scenic lakes and valleys.
Slovakia combines all the typical features of a grand European history with highly attractive nature and a traveller-friendly modern atmosphere.
