Without the assistance of dedicated volunteers, the Park's 25-mile trail system could not be maintained. These group work together to benefit the Park. For example, RTAG developed and mapped the trail markers. The trail project was funded and sponsored by the Cordelia Rotary Club. RTAG continues to work alongside the Rotary Club and Boy Scout Troop 864 to assemble and install the new trail markers and sign kiosks. The City of Fairfield has multiple volunteer opportunities whether you are a high school student looking for service hours, an individual, family or a bicycle club looking for a way to give back to the community and build lasting friendships!
