General

The official name of this popular rail trail is the John Wayne Pioneer Trail. A good portion of this trail is in the 100 foot wide Iron Horse State Park. Yup, it's confusing, but you're looking in the right place.

This gravel surfaced rail trail follows an old railroad line up to, and under, Snoqualmie Pass and takes you all the way to the Columbia River. There are plans to extend the trail all the way to Idaho. The surface is smooth gravel and the grade is never over 2.2%. Any bike will work on some parts of this trail, but wide tires are nice on the gravel, which can be a bit loose in certain sections.

The trail starts on the Seattle side at Rattlesnake Lake and climbs gently up towards Snoqualmie Pass, crossing over several old railroad trestles. Just before the pass the trail goes into the 2.3 mile Snoqualmie Tunnel under Snoqualmie Pass and comes out near Hyak. You'll need lights to go through the tunnel.

From Hyak the trail gently descends towards the Columbia River through the sunny and dry Eastern Washington Steppe. On the way you'll cross through several tunnels, over several trestles, and go through the Army's Yakima Firing Range.

On the east side of the Columbia, the corridor is managed by the DNR, and you need a permit to use it. If you contact their Southeast Region Office, they will send you a information packet with detailed maps. They will also have information on trail conditions.

This West Cascades part of this trail has a well maintained gravel surface and there are rarely any potholes. East of Snoqualmie Pass the trail has a variable surface. Most of the time it is nice hard gravel, but there are a few spots where the surface is a bit looser. Generally, the further east you get, the looser the trail surface becomes. East of the Thorp trailhead, you'll find little to no shade - it get's hot in the summer! East of Ellensburg, the trail becomes quite loose and riding can be difficult.

The ride between the South CleElum trailhead and the Thorp trailhead passes through the upper Yakima River canyon and is quite nice. There are two small tunnels in this section, and it's best to have a flashlight handy.

The Snoqualmie tunnel is closed annually from Nov. 1 until May 1, depending on conditions.

The Snoqualmie Pass tunnel needs significant maintenance and State Parks is seeking funding for the repairs. The work needed is to keep the lining of the tunnel from falling apart and could cost upwards of $10 million. The tunnel may be closed in the future for safety reasons and State Parks is considering on-grade reroutes to keep the trail open across the pass.

The Army owns the section of the trail between the Columbia River and Boylston and there are occassional rumblings that they will close it to public use.
