Started the hike at the Coal Creek trailhead, made my way through to the Red Town Trailhead and headed into the park. Followed Red Town Trail down to Indian Trail and passed the meadow restoration. Headed up Shy Bear Trail. Headed east on Fred's RR Trail. Stunning. After crossing Clay Pit Road headed further up to Cougars Pass and Tibbets Creek. Slid onto Bear Ridge and passed Fantastic Erratic. Continued on Bear Ridge (ultimate goal was Issaquah TC) with little problems until encountering the boundary marker. the trail suddenly became rock strewn and rooted. it's always a bit disconcerting when you look down at the trail and can't see any boot tracks. However, I wasn't about to retrace my steps to catch the Tallus Bridge trail, because...I'm stubborn. Hiked the slippery, ankle endangering mess of a trail all the way down, only to find a marker almost at the Renton-Issaquah Road that the trail was closed. Not only was it closed, it was a rehabilitation zone. No signage on the King County side of the trail noted this. I made it out of the forest, and on to a four lane busy road, and headed up to the TC. A little cooperation between county and city and a little signage would've been appreciated. Otherwise, a very pleasant, 12 miles.
