Now that it’s fall you might just be looking to take some unique autumn hikes. While October is still a ways away, why not make your next hike a little spooky? Like hiking in an abandoned tunnel. Ready to adventure? Let’s check out Snoqualmie Tunnel.

You’ll find Snoqualmie Tunnel inside of Iron Horse State Park in Snoqualmie Pass. If you’re unfamiliar, it’s a 1,612-acre park that the Chicago-Milwaukee-St. Paul-Pacific Railroad once ran through. Luckily for us, there’s a section of tunnel leftover creating the perfect hiking spot for adventure seekers.

Now you may be thinking, it’s only a tunnel, right? How can it be that spooky? Well, it’s a 2.3-mile-long tunnel that runs directly through a mountain. That means it’s unlit and even cold in some parts. Without lighting, the light at either end of the tunnel gets smaller and smaller until you’re completely surrounded by darkness. It’s easy to get disoriented and hikers have been known to get turned around.

If you’re up for the adventure it’s a great spot to check out during the fall. We recommend bringing layers and a headlamp of course. But be sure to turn it off halfway through the tunnel to give yourself the full experience. Now keep in mind, the tunnel does close for winter or at signs of snow so we recommend going sooner rather than later. You can learn more by clicking below.
