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. Stay to the right and cross another bridge over the inlet stream to Alder Lake. After this continue to follow the path which may have some red blazes along the way. The path here follows a woods road at some distance from the lake shore. You will walk out into an open “field” near the dam. Walk toward the dam and cross over it to get back to the “lawn” and the path back to your car.
