Trail Patrol volunteers assist Park rangers by hiking in County Parks to note safety issues along the trails. These volunteers also serve as park ambassadors by answering visitor questions, providing trail recommendations and hiking directions. Volunteer hours are flexible. This is a wonderful opportunity to hike the trails you love while helping San Mateo County Park rangers. Prospective volunteers are required to complete an application, an interview and training hikes. For more information, contact Carla Schoof at cschoof@smcgov.org.
