The Friends of Los Peñasquitos Canyon Preserve is a volunteer organization which has been protecting the preserve for more than 25 years. The Friends assist the city and county rangers through such activities as leading interpretive walks, performing wildlife and other scientific studies, removing invasive exotics and replanting with natives, installing kiosks, and coordinating Scout projects. Past scout projects have included building small bridges, installing interpretive signs, building and installing owl boxes, and restoring trails. The Board meets bi-monthly and welcomes new volunteers in any capacity.
During the rainy season please check the Trail Status before heading to the preserve.
