[3] The Maymakan originates in the southwestern sector of the Dzhugdzhur mountains.

It heads roughly northeastwards as a mountain river, flowing tumultuously with rapids and riffles through rocky gorges.

About two thirds down its course it bends slightly and flows northwards, meandering in the floodplain in its lower course.

[3][1] Finally it flows into the left bank of the Maya 479 km (298 mi) from its mouth in the Aldan.

[1][6] Taimen, pike, perch and lenok are the main fish species found in the waters of the Maymakan.
