South Twin Peak is one of the two peaks that comprise the Twin Peaks massif located just northeast of the Columbia Icefield in Jasper National Park. The other higher peak is named North Twin Peak (3,684m).
The mountain was named in 1898 by J. Norman Collie and Hugh M. Stutfield.
The normal route is a ski mountaineering climb on the eastern slopes of North Twin, and then a traverse to the South Twin, although an ice axe is recommended for the narrow connecting ridge.
