Cape Chelyuskin at the tip of the peninsula is the northernmost point of the Asian mainland.

The peninsula, covered mostly with tundra and drained by the Taimyra River, forms most of the Taimyr Autonomous Region (1992 pop. 53,000), 332,857 sq mi (862,100 sq km). The region also includes the islands between the Yenisey and Khatanga gulfs, the northern parts of the Central Siberian Plateau, and the Severnaya Zemlya archipelago.

Taimyr's economy depends on mining, fishing, and dairy and fur farming as well as such traditional activities as reindeer raising and trapping.
