History and scenery
Believe it or not, this is the only country in Europe that hasn't changed it's name since being established some 1300 years ago.
It's in the middle of the Balkans and it is a showcase for what they have to offer: tall mountains, long beaches, a blend of oriental charm and chaos mixed with Western European order and not too much of either.
Setting off from the capitol Sofia, you are in the geographic center of the whole peninsula, between three 2000m+ mountains. Possibly the best place to rent a motorcycle from on the whole Balkan peninsula
