Mountains to Sound Greenway

The Mountains to Sound Greenway is a conservation corridor that runs from Seattle to Ellensburg, linking forests, farmland, and communities along Interstate 90. The area offers numerous hiking and cycling routes as well as recreational spaces that connect across this network.

The greenway began in 1990 when concerned citizens hiked from Cascade Crest, leading to the formation of the Mountains to Sound Greenway Trust the following year. The organization worked to establish this corridor as a protected conservation area.

Several Native American nations practice traditional fishing and hunting throughout the corridor as part of their ongoing way of life. These activities shape how people connect with and move through the landscape today.

The corridor is accessible from multiple entry points and offers year-round opportunities for hiking and cycling at various difficulty levels. Plan to spend enough time exploring since the area spans a long distance with different terrain types.

The area connects multiple watersheds in one continuous network that stretches from the mountains to the coast, linking inland and coastal ecosystems. This integration of watershed systems across a single corridor is uncommon for the region.
