Frequently Asked Questions
These specially designed trips were created to highlight the rich history, ecology, and recreational opportunities in the Mountains to Sound Greenway. See our current offerings. For all trips, we'll be blending outdoor trips and on-the-ground education with an incredible opportunity to meet and hike/bike alongside other Greenway residents and passionate supporters of this region. The Greenway Trust will be handling all the logistics for these trips, including shuttle service from your car to the start of the hike or bike, educational opportunities along the way, and BBQs at the end of the trip. Learn more about our upcoming trips.
The Mountains to Sound Greenway stretches over 100 miles along Interstate 90 from the shores of Puget Sound in Seattle, over Snoqualmie Pass and into Central Washington. The Greenway encompasses protected and working forests, farms, historic sites, lakes, campgrounds, rivers, trails, wildlife habitat and vibrant communities. Because of this magnificent scenic beauty and easy access to nature, the stretch of I-90 within the Greenway is a designated National Scenic Byway.
The Mountains to Sound Greenway Trust is the nonprofit organization based in Seattle that helped to protect these lands and preserve them for public benefit. The Trust leads and inspires action to conserve and enhance the landscape from Seattle across the Cascade Mountains to Central Washington, ensuring a long term balance between people and nature.
Trips range from easy to moderately strenuous, mostly because of the distance of each hike or bike ride--see your trip's information page for its level. For all trips, participants should be able to hike or bike the total distance, while carrying a daypack full of water, snacks, and the "10 Essentials." We always encourage participants to travel at their own pace; with so many participants at each event, there will be plenty of "hares" and plenty of "tortoises". If you feel comfortable that you can finish this hike or bike ride at your own pace, you should be fine.
All participants should be in good physical condition and accustomed to hiking and/or biking. If you are unsure if these trips match your current skill or ability level, please feel free to with any questions you have.
For the Snoqualmie Tunnel Trip, you need to be able to bike at least 20 miles. That said, the trail has a mostly downhill, railroad grade the whole way and therefore isn't a strenuous ride (although it is long). There will be plenty of opportunities to stop and enjoy the scenery, learn about the local ecology and history, and have hydration breaks. We always encourage everyone to bike at their own pace. Estimated pace for bicycling will be 7 mph, meaning participants should anticipate biking for 3-4 hours (maybe a little more, once you add in the stops along the way).
For the Tiger Mountain Trip, you need to be able to hike at least 9 miles. The trail is 9 miles long with 1,300 feet elevation gain--it has moderate climbs at the beginning and in the middle, with the rest either relatively flat or gently rolls up and down. So while it is long it is only moderately strenuous. As always, everyone is encouraged to hike at their own pace and there will be plenty of opportunities to stop along the trail for educational talks, and hydration/food breaks. Estimated pace for hiking will be 2 mph, so participants should expect to be hiking for 4-5 hours (maybe a little more, once you add in the stops along the way).
Yes! As long as the children or teens are able to finish the hike or bike under their own power, they should be fine attending (although all youth under 16 need to be accompanied by an adult).
That said, the Trips can be challenging (especially the moderately strenuous ones), with participants needing to be able to hike or bike longer distances while carrying a daypack with water, food, and other “10 essentials.” We recommend that you take your children or teens out for a similar activity and assess their interest and abilities before signing up for the Trips. Because of the length of the trips, we do not recommend bringing children under the age of 12, unless they have proven experience successfully completing longer trips. If you have any questions about this, please feel free to .
The Mountains to Sound Greenway Trust is dedicated to providing an affordable, high quality outdoor experience for as many people as possible. We are offering a limited number of financial scholarships for those who demonstrate financial need and/or extenuating circumstances, especially youth.

A full list of items to bring will be emailed to you prior to the event. We recommend you wear weather-appropriate clothing (as well as extra layers in case the weather changes) and comfortable, sturdy hiking or biking shoes. If you have new boots, please break them in before the trip to minimize the chance of blisters or discomfort. You also need to bring a backpack with food, water, extra layers, and the "10 Essentials".
Bike trip participants will also need a bike, helmet, and headlamp (for the unlit tunnel). Your bike should be either a mountain bike or a hybrid style, because of the loose gravel on the trail makes it really hard to use a road bike (with the skinny tires).
While there will be snacks in the morning and a BBQ at the end of the hike/bike, we highly recommend you bring extra snacks and, if your trip isn't scheduled to get back to the BBQ until mid-afternoon, a big, hearty lunch. You'll be hungry!
All participants must also bring a signed liability waiver. We'll collect it at check-in.
You can borrow from a friend or rent a bicycle from your local bicycle shop. Make sure you test it out prior to the event to ensure it fits you and will be comfortable and safe for the event.
You park at the end point, we shuttle you and your gear to the start and you hike/bike back to it. Please arrive to the starting point at least 15 minutes prior to the shuttle departure time to allow enough time to find parking, sign-in, and grab a snack. For all bike trips, please arrive earlier, as you will need extra time to load your bike onto the shuttle before leaving.
Events will run rain or shine. Event leaders will contact you if there is a change, but we don't anticipate any. It's a great day in the Greenway either way!
No. Sorry, but we must keep this a people-only event. No pets will be allowed other than service animals.
We will have staff and volunteers trained in CPR and First Aid, ready to deal with blisters and other injuries. They will be identified as first aid leaders at the beginning of the event and will be hiking/biking along with the group during the trip.
