Four major European geographic regions meet in Slovenia: the Alps, the Dinarides, the Pannonian Plain, and the Mediterranean. Although on the shore of the Adriatic Sea near the Mediterranean Sea, most of Slovenia is in the Black Sea drainage basin. The Alps—including the Julian Alps, the Kamnik-Savinja Alps and the Karawank chain, as well as the Pohorje massif—dominate Northern Slovenia along its long border with Austria. Slovenia's Adriatic coastline stretches approximately from Italy to Croatia.
