CANCELLATION- The San Mateo County Parks Department informed us that they will be closing areas of San Bruno Mountain State & County Park south and east of the Guadalupe Canyon Parkway (including the Summit Loop and Ridge Trails) on Saturday, October 19th due to a Red Flag Warning of high fire danger. This event has been cancelled as it makes use of these trails.

Meet at the main entrance parking lot just past the Ranger Station. Remember to put on sunscreen, wear layers, bring water and a snack.
