Iron Horse State Park: Snoqualmie Tunnel Professional Review and Guide

"Ever want to go on a night ride- during the day? The Snoqualmie Tunnel, on the Milwaukee Railroad grade, affords that unique opportunity with a 2.3-mile tunnel through, not over, Snoqualmie Pass. The flat, smooth, gravel rail-trail is suitable for beginners, but provides an experience that even advanced-level riders won't find elsewhere. Advanced riders can also continue west to the tunnel for more than 15 miles each way.

For miles of decidedly non-flat riding nearby, tackle the roads and singletrack at nearby Ski Acres Mountain Bike and Hiking Center. The area has hosted national- and international-level competition, both cross-country and downhill. Be like the downhillers and take the ski lifts up, or be like the cross-country riders and climb from the base. Even in the heat of summer, the tunnel is dark and chill; lights and warm clothing are essential. Scenery: Alpine views on the way to the tunnel, darkness inside, Keechelus Lake nearby."

Our family had a great time on this ride. We had our 4 year old son in a bike trailer and our 7 year old daughter on a tag-a-long. The gravel surface was easy to ride on and the tunnel was "spooky" enough to capture the interest of the kids. Every one says this, but pack a sweater or coat for inside the tunnel. It was almost 80 degrees, but it was cold enough inside the tunnel to see my breath. Also, we continued west after we completed the tunnel and the going was so easy, that we almost forgot it would be uphill on the way back. Those three miles back up to the tunnel pulling the kids were pretty hot, but still not bad. Rail trails are the best!
If you can get to this trail do so. The tunnel is a blast to ride through just be warned that there is spots where cold water(ice cold) drips down from the ceiling of the tunnel. The trail from the tunnel to the lower end of the trail is a decent grade. Not too steep but constant enought to give a good work out. There are also a couple of bridges that you go across as well. All in all I recommend this for at least a must do day trip. Just start at exit 38 on I90 that way the return is down hill. Also it kinda makes the tunnel a reward for the 15 miles up hill.
