Enjoy a beautiful singletrack along the east side of Alder Creek. From the main parking area, follow the Ninebark Trail into the park and across the bridge over Alder Creek. Immediately turn left - this is the start of the Alder Creek Trail. The trail is a narrow, fairly level singletrack that weaves in and out of the trees and willows along the bank. In about 0.2 miles the trail ends where it meets the Gudde Ridge Trail.

Coyote brush, blackberries, and seasonal flowers like lupine and California Poppies are common. Watch out for poison oak! Birds are the most typical fauna, especially juncos, chickadees, finches, towhees, and nuthatches. Occasionally acorn woodpeckers can be seen, as well as hawks, jays, crows, etc. Other fauna include deer, coyotes, ground squirrels, etc.
