The trail winds along steep valley walls above Deep Creek to the Davis Creek Divide. From there the trail drops down into the West Boulder River. Pine Creek is one of the most popular trailheads in the area. The access road is located about one mile south of the town of Pine Creek on the East River Road. Pine Creek Falls is just a short hike from the campground, and for the hearty hiker Pine Creek Lake is another three or four steep miles up the mountain.
Mill Creek is one of two corridors that extend deep into the wilderness area.
From the Mill Creek drainage hikers and horseback riders can get to numerous trailheads that provide access to dozens of lakes and destination points. One of the most popular is Thompson Lake, up the west fork of Mill Creek. Elbow Lake is also popular and is located at the base of Mount Cowan, one of the most challenging peaks in the area to climb. Mill Creek also provides access to Passage Creek Falls. The Snowbank Campground is located along the road up Mill Creek.
