The rivers rise mainly in the highest mountains, and flow into the Black Sea (via the Danube) and into the Aegean Sea. Bulgaria has 526 rivers longer than 2.3 km. The only navigable river is the Danube, which flows along the northern Bulgarian border.
There are good opportunities for adventure tourism: wild water rafting and canoeing, diving, delta- and para-gliding in the valleys of the Vatcha, Iskar, Chepelarska, Struma, and Mesta rivers.
