The Sisters Trails Alliance is a non-profit organization, whose mission is to connect people and communities to each other and their natural surroundings. We plan, build and maintain multi-user, non-motorized trails in and around Sisters, Oregon.  

Upcoming events


STA is cancelling or postponing upcoming events and evaluating activities at least a couple of weeks in advance. Please check the Upcoming Events section for updates. Stay safe!

Thanks to our friends at Central Oregon Trails Alliance for providing these suggested guidelines for recreating responsibly:

1. STAY HOME – this is the safest option.
2. KEEP IT LOCAL – if you have to drive to ride, you’re probably too far from home! Take a walk or ride your bike around your neighborhood.
3. DISTANCE - most trails are single-track and it’s not possible to adhere to the minimum 6-foot distancing rule unless you go way off trail and that’s a bad idea. Additionally, many trails are muddy and need to dry out before riding. If you must be out, please use some of the numerous forest roads as this will allow for better distancing.
4. MORE DISTANCE - The Forest Service has closed the trailheads and day use areas and is no longer servicing their restroom facilities. Please respect these closures for the health of our community.
5. RESOURCE PROTECTION - if you’re out on the trails there’s a distinct risk of injury that would cause already constrained emergency resources to be depleted and possibly create exposure to COVID-19. Dial it back, the trails will be there.

Beware of Muddy Trails!
