STA works in the Sisters Ranger District in the Deschutes National Forest. Our 300+ member volunteer corps are hikers, cyclists, snowshoers, trail runners, skiers, equestrians and nature lovers who donate their time, financial resources and labor to help build and maintain 200+ miles of trails in Sisters Country. We believe everyone should have access to our beautiful outdoor spaces.  Forever.

Show your support through a financial donation and by joining one of volunteer committees or work parties.
