Bulgaria, located in southeastern Europe on the Balkan Peninsula, shares borders with Romania, Serbia, North Macedonia, Greece, Turkey, and the Black Sea.

The country is celebrated for its mountains, including the Rila massif with Mount Musala—the highest peak at 2,925 meters—as well as its plateaus and the Danubian Plain. The temperate continental climate makes spring and summer especially pleasant for visiting, with temperatures ranging from 20 to 30 °C. Bulgaria is a member of the EU, NATO, and the United Nations.
