Paraguay

From Wikipedia: Paraguay is a landlocked country situated in central South America, surrounded by Argentina, Bolivia, and Brazil. A country of big rivers, green landscapes, folklore and a rich indigenous culture, it's relatively small compared to its neighbours, with an area of 406,752 km2 – about the same size as Germany. Paraguay is lacking in world-famous attractions, and tourist-oriented establishments are few and far between. But those visitors who do come will be rewarded with an experience of the real South America: colonial history, ruins of missions, vast wilderness, and a strong mix of European and indigenous cultures.
