This was a really fun, easy hike. Some stretches were muddy, but overall it was sunny and dry. We parked at Red Town and walked across the street to the Coal Creek Trail. Very soon after starting we saw a hole where a coal mine used to be. It was neat to look in, but only went to a depth of maybe 10 ft. It appeared to have been sealed. Other highlights included coal on the ground, waterfalls, a car and a metal roof in a field, wooden pedestrian bridges, a train wheelset a tree, and skipping rocks in the stream. We hiked the whole trail and back in about 2-2.5 hrs, and it was pretty flat and well-maintained. We encountered probably 20 other hikers in passing.
