From the parking area go east on the singletrack by the bathroooms. The trail starts with an 8mi climb on thight sometimes loose singletrack, there are alot of weeds on the sides of the trail that will get caught in your drivetrain. After are a few stream crossings, that were dry when I went, there is a livestock fence to go through. After crossing a couple of jeep roads at the top and going through another livestock fence, continue on the trail for a decent into the next valley. At the bottom be ready for another climb of about 4mi. Decend on Triple Fork trail for about 8mi to its trailhead. Here you will have to go to your right out of the parking area for a ride on the road back to Harrington Fork parking area, about 4mi.
