Sacalin Island is a newly formed island in the Black Sea, right off the coast of the Romanian Danube Delta, off the Sfântu Gheorghe branch.
[1] Initially Sacalin was made up of two smaller islands, Sacalinu Mare [Greater Sacalin] (1400 ha) and Sacalinu Mic [Lesser Sacalin] (90 ha).
The Romanian government has declared the area an ecological reserve Sacalin-Zătoane (21410 ha) and no settlement is permitted on the island.
Sakalin-Zătoane Island is surrounded on all sides by lakes, fishponds, rivers, canals and the Black Sea.
Therefore, it is the largest island in the Black Sea.
