Hiked the entire 23 mile Tarbell Trail loop today. Beginning at the Tarbell Picnic Area, I hiked down to Hidden Falls, up to near Sturgeon Rock, down to the Grouse Vista Trailhead, up Larch Mountain to the picnic bench on the East side, down to the Rock Creek Campground and then back up to the Tarbell Picnic Area. The weather and trail conditions were great and the hike took me about 10.25 hours.
There is a logging operation going on between Cold Creek and Rock Creek that the trail goes through but its pretty easy to stay on the trail even through the clear cut.
