Description

This is a wide gravel fire road that provides access to other trails in the Eastport region of Sibley Volcanic Regional Preserve. The trail starts at the parking area off of Pinehurst road. Pass through the hiker gate and travel north into the park. In 100 feet meet the first junction. Left (northwest) is the Pacific Pea Trail near the bathroom. Straight (north) is the start of the Gudde Ridge Trail. The Ninebark Trail turns right (east) and crosses Alder Creek.

Once you have crossed the bridge you'll reach another junction. The Alder Creek Nature Trail goes left (north) and follows the creek bank. The Ninebark trail continues straight (northeast) and begins climbing. In another 100 feet reach the junction with the Kitchen Orchard (left, north) and the Leatherwood Creek trails (right, south). Continue straight and in 50 feet pass a large, fenced in storage shed. Continue up the hill, past some black cisterns on the right hand side, and reach the end of the trail, where it meets the top of the Leatherwood Creek Trail.

Flora & Fauna

Birds are the most typical fauna, especially juncos, chickadees, finches, towhees, and nuthatches.
