Middle Sister (also called Second Sister), is the only peak of the Three Sisters accessible to walkers. Seasoned scramblers consider it "boring," meaning easy. Nevertheless, be up at the crack of dawn for this one, which is a very long but surprisingly easy trudge up a rocky creek bed and on scree.
Start: Stewart Creek Landing. This is a construction area and access is frequently changing. Drive as far as you can on Three Sisters Parkway through the Stewart Creek area currently under development. Park by the gate. Follow the old haul road to the Stewart Creek turn-off.
Difficulty: The trail is now a creek bash most of the way. Some bits of the old trail do still exist on left side when going up Stewart Creek, but it's definitely a chore to travel compared to before. Pink flagging helped find easiest route (as opposed to the cairns that are all over the place.
Note: High up in the drainage, right below where the scree begins, there is serious erosion along the creek bank and the terrain is now extremely steep and awkward. It is better to go up on the open hillside on the right side close to the trees, then angle across back into the drainage when you're well past the steep ugly looking parts.

Please refer to the trail description in the guidebook, especially for unofficial, off-trail hikes.
