East of San Diego and Alpine near Buckman Springs, the 3,250 acre Lake Morena County Park has a great 20 mile mountain bike course. Because of its location on the east slope of the Laguna Mountains, the park shows characteristics of desert, coastal, and mountain habitats. This chaparral woodland is home to a variety of animals. Bald eagles, mountain lions, rattlesnakes, and many migratory waterfowl can be observed in the remote wilderness.
Since this route shares trails with the Corral Canyon OHV Area, keep an eye out for ATV and dirt bike riders.
