Hiking – Twin Sisters TH - Twin Sisters and South Sister

This is an out and back hike, mostly on a well-established trail.  There is a trail to the west summit.  The out and back from the east summit to the south summit will be off-trail.  There is some rock hopping and Class 2+ scrambling to get to the east summit, which is the highest summit on Twin Sisters Peak, as well as on the off-trail section over to the South Sister.
