Cost & Transportation

Program Cost

The Mountains to Sound Greenway Trust works hard to provide the best possible value to our school partners. Our goal is to remove barriers preventing students from accessing the outdoors, not to create new ones. To make this happen, we subsidize the cost of our program through a combination of gifts and grants from generous donors and supporters.

Our program fees are per class and are based on a school’s percentage of students participating in the National School Lunch Program (a.k.a. their “free and reduced lunch rate”). Find your school’s percentage at OSPI Washington State Report Card.

If your school has a free or reduced lunch rate of 50% or higher, the Greenway Trust may be able to pay for your field trip and stewardship event buses. Contact us to learn more.

Free Wheels to Water Buses

Each year King County provides a limited number of public buses through their Wheels to Water program to transport classes to field study trips. To be eligible for a Wheels to Water bus, schools must have a free or reduced lunch rate of 35% or higher. If you are interested in using a Wheels to Water bus, please contact us as soon as possible.
