What are the Explore the Greenway Trips?

These specially designed trips were created to highlight the rich history, ecology, and recreational opportunities in the Mountains to Sound Greenway. 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/bike/float, educational opportunities along the way, route map, food, and t-shirt.

What is the Mountains to Sound Greenway?

The Mountains to Sound Greenway, a newly designated National Heritage Area, 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.

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 Greenway 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.

How difficult are the trips?

Trips range from moderate to moderately strenuous, mostly because of the distance of each hike or bike ride.  See trip pages for specifics about each.

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 send us an email with any questions you have.

Are youth allowed on the trips?

Yes! Our recommended minimum age is 12 years old. They should be able to finish the hike or bike under their own power, carrying a daypack with water, food, and other “10 Essentials.” 

All youth under 16 need to be accompanied by an adult.

Exceptions for Hike and Bike Trips

If you are considering bringing a youth who is younger than 12 years old, we recommend that you take them out for a similar activity and assess their interest and abilities before signing up for trips. Some children younger than 12 have proven experience successfully completing long, strenuous trips like these. Or are young enough to be carried in a tow-behind-bike carrier or on your back. In these cases, if you think your child will be able to complete the trip you may register them, but please add a short note on the registration form with details about their experience or send us an email.

Exceptions for Float Trips

Children must be able to swim and paddle in order to attend this trip – the Upper Yakima Canyon is the fastest-flowing stretch of the Yakima River, so we do not advise bringing small children who may be upset or frightened by a fast paced, bumpy float. Our recommended age is 12 years old, but we recognize that some children may be more experienced on the water and are tall enough to paddle effectively. In these cases, if you think your child will be able to complete the trip you may register them, but please add a short note on the registration form with details about their experience, or send us an email.

What does the payment cover?

Each trip has a fee to participate. These costs pay for the shuttle service from your car to the start of the trip (since you’ll park at our end destination, and then hike/bike back towards it), your t-shirt, route map, and food.

Please note that these fees are NOT tax-deductible donations, as they are paying for a service. To make a tax-deductible donation to the Greenway Trust, please visit our online donation form or mail in a donation.

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. Contact us for more information.

I have now registered and paid. When will I get additional details about the trips?

What if I need to cancel?

If you are no longer able to participate, please let us know as soon as possible by emailing us.

What do I bring?

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 mountain bike and helmet. For the Snoqualmie Tunnel Trip you will also need a strong headlamp and/or bike light, for navigating the unlit tunnels. For all biking trips, we recommend all riders use a mountain bike because of the wider tires and increased stability, since the trails are packed gravel with several loose sections. Experienced riders who are comfortable biking in these conditions may use a hybrid bike. Road bikes (with their thin tires) are not allowed for safety reasons–it’s too easy to fall.

Float trip participants will need to bring a swimsuit, sun hat, sunglasses, shorts, and shoes that strap to your feet, such as old tennis shoes, water socks, or sandals. Please check the weather forecast beforehand and, if temperatures are predicted to drop, do not wear cotton clothing; the cotton will remain cold, and chill you.

All participants must also complete and sign a liability waiver, available online prior to the event. The link will be emailed to you.

What if I don’t have a bike?

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.

Snoqualmie Tunnel trip: Compass Outdoor Adventures is offering our participants a discounted mountain bike rental of $50 and will bring them to the start location for you. Email us for details.

What if I don’t have a Personal Flotation Device (PFD)?

PFDs will be provided on the float trip. If you have your own, you are welcome to bring it, but are responsible for making sure it goes home with you.

How does the shuttle service work?

You park at the end point, we shuttle you and your gear to the start and you hike/bike back to your car. (For the float trip it is the opposite: you will park in Cle Elum, float to Thorp, and then be shuttled back to your cars in Cle Elum.) 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.

 What kind of food will be included with the trip?

Each meal is a little different, but we’ll have meat, vegetarian, and gluten-free options and (non-alcoholic) drinks.  Please email us if you have questions.

What happens if the weather is bad?

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!

Can I bring my dog or other pet?

No. Sorry, but we must keep this a people-only event. No pets will be allowed other than service animals.

What happens if I get a blister or get hurt during the event?

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.
