Thanks to Joe Poulton for adding this peak.

Similar driving directions as for the North Twin Sister. But in the summer you can also bike the 8 mile Blue Mountain Road which is relatively flat compared to Road 38 approach. The South Twin is the highest peak in the Twin Sisters Range. The easiest route is the West Ridge. All the glaciers are on the East side of the Range, so you don't need glacier gear for west side routes.

Thanks to Joe Poulton for this description.
