Connecting the trails network across the Central Puget Sound region to improve health, community, quality of life, mobility, and access for all.


The Leafline is an interconnected, intuitive, well-traveled, and treasured trails network spanning the Central Puget Sound region, providing equitable access, health benefits and recreational opportunities for all.


We are working together to maximize our collective impact, develop a shared map vision for trails, enhance user experience, grow awareness of the Coalition, and work together to fill gaps in the trails network.


Leafline Trails Coalition is a fiscally sponsored project of the Seattle Parks Foundation, a 501(c)3 nonprofit.
