General Description

Notes: This loop is designated for mountain biking. It offers a mixture of dirt roads and singletrack.

In Fraser, head west at the traffic light and continue under the railroad tracks. Take the first right. Follow this route to County Road 73. Turn left. This is a dirt road with gradual climb. Go approximately 2 1/2 miles to the St. Louis Campground. Follow the road down toward the campground. Just before you pass a gate, turn right onto a single track trail. This is the beginning of Creekside Trail, which gently follows the bank of St. Louis Creek. The trail eventually crosses an irrigation ditch and then winds around on several paths until it meets County Road 159.

Turn left and follow County Road 159 over a bridge and up a gradual hill. At the top of the hill take a right and follow King Creek Road for about 2 1/2 miles until it meets up with County Road 159 again. Continue straight for about 1/2 mile. Turn left onto Zoom Trail. This singletrack trail winds its way down for just over 1 1/2 miles. You'll come to a 'T', turn right and follow the rest of the Chainsaw Trail down to Elk Creek Road. Turn left and continue downhill to Fraser.

Directions from Fraser: Head west at the traffic light and continue under the railroad tracks. Take the first right. Follow this route to County Road 73.
