When and Where to Meet

Participants will meet and park at South Fork in North Bend (14303 436th Ave SE, North Bend, WA 98045). Carpooling to South Fork is highly encouraged and bicycle parking is available. Keep an eye out for signage and staff members assisting with parking.

Please arrive at South Fork between 8-8:15 a.m. Welcome remarks will begin at 9 and the shuttle buses will leave at 9:15 a.m. Make sure to leave enough time to find parking, get signed in, complete your waiver if necessary, and get your bike loaded. Come early for some morning snacks and coffee!

From South Fork, participants will ride a shuttle up to the Hyak entrance to the Snoqualmie Tunnel and then bike the 27 miles back to your car and post-event celebration.

What to Expect

The Mountains to Sound Greenway Trust hosts several Explore the Greenway Trips every year to highlight the incredible treasures found in our region. On August 5, we will be biking 27 miles on the Palouse to Cascades State Park Trail (formerly known as the John Wayne Pioneer Trail) and Snoqualmie Valley Trail, beginning at Snoqualmie Pass and ending at South Fork. The trip includes a journey through the 2-mile-long historic Snoqualmie Tunnel and spectacular views of the surrounding Cascade Mountains.
Since it is a one-way trip, we are providing a morning shuttle service. We’ll meet at South Fork (also our end destination for the day), and you’ll leave your car there. You (and your bike) will take one of our shuttle buses up to the beginning of the tunnel.
Once up at Snoqualmie Pass, we’ll head through the tunnel and bike back down to South Fork. There will be numerous spots along the way to stop, enjoy the views, and ask Greenway leaders questions about the local history, recreation, and ecology of the areas you are biking by. You will arrive back to South Fork in early afternoon, depending on your biking pace. We’ll have a taco bar waiting for you (from 1-3 p.m.) so you can hang out for a bit longer and enjoy the company of your fellow bikers!


We want everyone to enjoy a fun and safe experience on this bike ride. Please review these safety recommendations so you can “bike smart.”

  • Bike at a responsible speed for this gravel trail – Do not race, both for your safety and those around you
  • Be respectful of other trail users, including cyclists, hikers, and horse riders – not everyone goes at the same pace
  • If you need to pass someone, give them plenty of warning (use your voice or a bell) and give them lots of space as you pass
  • If there are horses, ask the rider if it is okay to pass before doing so
  • Before entering the tunnel, turn on your headlamp/bike light and remove sunglasses
  • Enter the tunnel in small groups and go slow – Give your eyes enough time to get used to the darkness and to get a feel for your position on the trail
  • Avoid biking too close to the walls of the tunnel – Loose gravel accumulates there and might catch your tires
  • Travel only in small groups in the tunnel – If you find yourself too close to other trail users, either pass them or back off a bit to give more space between your groups


The Snoqualmie Tunnel Bike Ride will happen rain or shine. Be sure to bring appropriate clothing, water, sunscreen, sunglasses, and anything else you need to stay comfortable. In the case of extreme weather or wildfire smoke, we will contact all participants in the event of a cancellation.
