Friends of Ruffin Canyon

Friends of Ruffin Canyon is a group of Serra Mesa residents who volunteer to look after Ruffin Canyon and the nearby Library Canyon. Ruffin Canyon is City-owned open space between Serra Mesa and Mission Valley.

Members remove trash and invasive plants, plant native plants, and look after a native plant garden beside Taft Middle School. The group holds cleanups twice a year. It also put together the Serra Mesa trails guide.

The group's first leaders were among the residents who pressed the City Council to dedicate the canyon as open space in 2003. Starting in 2007, members pushed for a trail linking Serra Mesa to Mission Valley. The trail opened in April 2026.
