It flows through a sparsely populated tundra landscape in a predominantly northerly direction. Finally the Tschaun reaches the Tschaunbucht on the coast of the East Siberian Sea .

The main tributaries of the Tschaun are Ugatkyn from the left and Milguwejem from the right. The Tschaun has a length of 205 km. Its catchment area covers 23,000 km².
