Trail Building and Restoration

The COSCA system includes more than151 miles of trails, and we’re making that number larger every year! During the Fall and Spring Trail Work Days, volunteers come out to help build new trails for everyone to enjoy. Sometimes we instead go out to repair trails that were damaged during severe winter weather. Groups including local businesses volunteer their time to help the trails as a way to give back to the community.

Our trail building and restoration activities rely on volunteers to help out! If you would like to see more and better trails, we hope you’ll want to pitch in!
