Also known as the John Wayne Pioneer Trail, this rail-trail runs along the I-90 corridor in the bed of the former Milwaukee Railroad. Starting at the Rattlesnake Lake parking area, the trail climbs very slowly up to just below Snoqualmie Pass, where it enters a 2.3 mile tunnel (now reopened). On the way, it crosses a number of dizzyingly high trestles over mountain streams. A number of rock faces along the way are popular with rock-climbers, and they and their gear may be scattered along the trail sides nearby.
Riders planning to enter the tunnel should remember to bring warm waterproof clothing, as it is cold and damp inside the tunnel, and a headlamp and backup light.
To Rattlesnake Lake: Take exit 32 from I-90 and turn south on 436th Ave SE (Cedar Falls Road). Follow 3 miles to Rattlesnake Lake, where the road ends at a gate leading to the Cedar River Watershed Education Center. Turn left into the Iron Horse Trail parking, then immediately right into the RV/Trailer Parking area. There are six pull-through spots, though on busy weekends "normal" vehicles will sometimes park there, inconveniently.
Open. The pass tunnel reopened on July 5th 2011, and should be open for the season until November 1st.
