Difficulty: This hike is rated MODERATE because it is almost 5 miles long and has some ascents on the Millbrook Ridge Trail. There may be wet or muddy areas along the way.
Trail Surface: The trail surface up to the Millbrook Ridge Trail is more of a path and is free of large stones and tree trunks consisting mostly of small stones and dirt. The Millbrook Ridge Trail is a hiking trail which may have some larger rocks and tree roots. The trail is often wet and muddy in places.
Hike Description: Walk out the end of the parking area toward the lake on the path. The stonework on the left is the remains of the Coykendall Mansion that was in such disrepair that the state burned it several years ago. Ahead of you is Alder Lake which is very popular for camping, fishing and hiking. Walk down the path to the left of the lake. Continue to follow the path as it curves around the lake clockwise. You will walk over a bridge that span a small stream that enters the lake. At .8 miles the yellow Millbrook Ridge Trail turns to the left. Turn left on the Millbrook Ridge Trail to begin a 1.4 mile ascent that gains 530 feet. The trail is never very steep and there are several level areas along the way. The trail parallels Alder Creek for most of the hike. There are several beaver meadows along the way on the right side of the trail. You may also find a beaver pond on the left side of the trail in one of the more level areas. At 2.25 miles turn right on a short spur trail down to the Beaver Meadow Lean-to. You may want to walk away from the front of the lean-to on a path that walks down to a flat rock. This is a nice viewpoint and a place to relax before turning around to retrace your route back to the car.
