Ancient Thrace was partially located on the territory of modern Bulgaria, and Thracian culture provides a wealth of archeological sites within Bulgaria. In the second century A.D., the Bulgars came to Europe from their old homeland, the Kingdom of Balhara situated in the Mount Imeon area (present Hindu Kush in northern Afghanistan).
Bulgaria has changed swiftly over the last decade, though in the villages you can still find folk who ride the donkey to work, eat homegrown potatoes and make their own cheese. The difference now is that they wash it all down in front of a satellite TV.
When Bulgaria ran away with the topsy-turvy capitalist circus, no-one told its people they were swinging without a safety net. But what the visitor encounters now is a country struggling valiantly to adapt and people who remain remarkably hospitable in the face of social and economic chaos. Urban Bulgaria, especially Sofia, is much changed.
When To GoBulgaria has a temperate climate, with cold damp winters and hot dry summers. Spring (particularly April to mid-June) is an excellent time to visit. The days are getting longer, the weather is good, the theatres and other cultural venues are in full swing, off-season rates still generally apply, and locals are not yet jaded by waves of summertime visitors.
Summer (mid-June to early September) is ideal for hiking and festivals, but is the peak season for travellers from elsewhere in Europe. Temperatures can be very high during this period, the beaches on the Black Sea coast can get insanely crowded, and accommodation and camping grounds in coastal resorts tend to fill up.
September is perhaps one of the best months to see Bulgaria. The autumn trees are glorious, fruit and vegetables are plentiful, shoulder-season tariffs are in effect, the tourist hordes have returned home, and you can still swim and sunbathe at the Black Sea. The ski season begins in mid-December and can last until April.
