Two “Explore the Greenway” trips bring hikers and bicyclists outdoors to explore some of the scenic places in the Mountains to Sound Greenway.

In the Snoqualmie Tunnel Bike Ride and BBQ, 8:30 a.m. to 2 p.m. Saturday, June 29, discover the two-mile tunnel underneath Snoqualmie Pass, a remnant of railroad history. The biking trip will take riders through the tunnel’s cool darkness onto a 20-mile stretch in Iron Horse State Park, providing majestic views of the Cascades and a barbeque at Rattlesnake Lake.

Then, in the Rattlesnake Mountain Hike and BBQ, 8:30 a.m. to 3 p.m., Saturday, July 13, hike across this popular mountain. Most hikers know the trail up to Rattlesnake Ledge, but trip participants will be able to explore further and trek 10 miles across the mountain, enjoying sweeping views of the Snoqualmie Valley and Cascades, with educational stops and a well-deserved barbeque at Snoqualmie Point Park.

The Greenway Trust handles all logistics for trip participants, including shuttle service and barbeque at the end of each trip. Trips are $25/person. Register at mtsgreenway.org.
