Geography
The Tympylykan originates in an area of swamps and small lakes of the Central Yakutian Lowland. It flows first in a SSE direction and then roughly southeastwards to the south of the Linde within a wide floodplain. Towards the last stretch of its course it bends and flows northeastwards, meandering among marshes and lakes. Finally it meets the left bank of the Lena 1086 km upstream of its mouth in the Laptev Sea. The Lyapiske has its mouth roughly on the opposite side of the Lena.

The main tributaries of the Tympylykan are the 74 km long Achchygyi-Tympylykan and 66 km long Konkyus-Mande from the left, as well as the 52 km long Yogdyonyu from the right.
