The Vivari Channel links Lake Butrint in Albania with the Straits of Corfu, and forms a border of the peninsula of Butrint.
The channel flows in both directions, from the lake to the sea and vice versa during the rising tide. A pontoon is situated near the gate of the Butrint National Park. Two small forts are located in the southern part of the channel; both were built during the rule of Ali Pasha of Ioannina.
According to international organizations, the channel serves as the demarcation line where the Adriatic Sea ends and the Ionian Sea begins.
