Ljubljana Slovenia. When the former Yugoslavia broke up, several new state were created. One of them was Slovenia. It’s a small country with little fame to its name, but what a great opportunity for traveler to get to know a new country. Ljubljana Slovenia is a pleasant capital and one of the smallest in Europe, with less than 300,000 people. Ljubljana is a great introduction to the country. The city is quiet, but still has enough culture, dining, and entertainment to keep one happy. There aren’t many sights to see, just walking through this city reveals a laid-back populous and an old elegant city with a castle on top of the hill. Its climate keeps it relatively mild year-round, so a visit in any month is good.
