Columbia Basin

The Columbia Basin Chapter of Evergreen Mountain Bike Alliance was formed in the Spring of 2025 to serve the mountain biking community in the Tri-Cities and surrounding areas. Despite the region’s natural beauty and strong interest in riding, southeastern Washington has long lacked formally designated mountain bike trails. This chapter was created to help change that.

Building on the efforts of the Shrub Steppe Trails Alliance (SSTA), long-time local advocates based in the Tri-Cities, we are focused on expanding trail access and creating sustainable, multi-use and mountain bike-specific trails across Benton, Franklin, and Walla Walla counties. We believe that responsible trail development enhances outdoor opportunities, supports land stewardship, and brings communities together.

Our chapter is committed to building a welcoming and inclusive riding community. Through collaboration, education, and volunteerism, we aim to support sustainable trail development and ensure lasting access to the outdoors for current and future generations.

Join us at upcoming quarterly meetings, group rides, and volunteer events to learn more and support our work.
