Iron Horse Trail Tunnel

Iron Horse Trail Tunnel Professional Review and Guide

"Here’s a trivia question to toss out during your next trail party: The Iron Horse Trail and Washington’s other cross-state trail, the Pacific Crest Trail (PCT), intersect but never touch. Why not? Answer: Because the Iron Horse Trail runs through the 2.3-mile-long Snoqualmie Tunnel while the PCT rolls up and over the peaks south of Snoqualmie Pass. When you head out to explore this dark Iron Horse section, be sure you bring a flashlight—and a headlamp.

In fact, make sure every person in your party has a primary light and a backup— this is not a hike you want to do without light. The tunnel is long enough that you’ll be in deep, total darkness much of the way. And it’s easy to get turned around inside. I’ve seen savvy hikers bouncing like pinballs inside the tunnel because they couldn’t get themselves headed straight down the tunnel after losing their light."

The tunnel is re-opened and the hike through was awesome. Few must know tunnel is open again. Only my wife dog and I walked through it and encountered no one in and out. Easy hike, flat and solid. A great experience
