Tumac Mtn / Twin Sisters Lks,  William O Douglas Wilderness,  Aug 22, 1999 - Aug 23, 1999     page 1 / 20

Tom, Chris, Dad (Grampa) and I were prepared to spend two nights out. We drove over Chinook Pass, then down the Bumping River Valley, arriving at the Twin Sisters Lakes trailhead about 1:00PM. (If you plan to do the same trek, note that about 10 miles of the 19 mile drive off of highway 410 is very rough road.)
