Cerro San Luis Obispo

It is a common spot for hiking, jogging and mountain biking, and has steep terrain.

The large white "M" present on the east face derives from Mission College Preparatory Catholic High School.

Some time around 1900, an American Civil War veteran, G. W. Chandler, lived on the mountain and planted lemons and oranges.

The primary trail head is at the end of Marsh Street which provides access to the Open Space and Lemon Grove Loop.

There is a second road cut to the summit which has been abandoned and eroded to a narrow rocky path giving it the name "Rock Garden" and making it a popular descent for mountain bikers.
