Rock Mountain Preserve
ROCK MOUNTAIN PRESERVE is currently CLOSED due to safety concerns. The winter rains caused severe trail erosion and damage. Our limited staff and volunteers are working hard and hope to open Rock Mountain again soon. As we have limited staff and funds, we welcome any and all volunteers and donations. Please contact our offices at or call 760-728-0889.
Rock Mountain is accessed from Sandia Creek Road north of Fallbrook, about 1/2 mile past the Santa Margarita River crossing. This 78 acre preserve is crowned by a spectacular rock outcropping.
