NWTA Mission

To create, enhance, and protect mountain bike riding opportunities; to advocate for trail access; to promote responsible mountain biking; and to build, maintain, and ride sustainable trails.

Who We Are

Northwest Trail Alliance is an all-volunteer, non-profit organization based in Portland, Oregon. We are one of the Northwest’s leading mountain bike advocacy and trail stewardship groups. Created in 1988 as a grassroots club of local riders, focused on maintaining bike access to Forest Park – Portland’s renown urban park -, we have grown into a regional advocacy group, stewarding trails and advocating for trail access across a wide radius around Portland; from Forest Park and Powell Butte within the city limits of Portland, to the southern foothills of Mount St Helens, to the western slopes of Mount Hood, to Tillamook State Forest and Scappoose.

In December 2009, Northwest Trail Alliance enrolled in the newly launched chapter program of the International Mountain Bike Association (IMBA) and became the first IMBA Chapter in the Northwest.

Our Vision

  • For Portland, NW Oregon and SW Washington to become a recognized and acclaimed haven for mountain biking and off-road cycling.
  • To create awareness and a positive attitude towards all types of off-road cycling — with other trail users, with land managers and agencies, and with the general public.
  • To become a role model for other mountain bike and trail advocacy groups around the country.
