Cabrillo 3 is located in the South Coast region of California, in Cabrillo National Monument. The site is located within the Cabrillo State Marine Reserve. This site is off limits to human visitors and recieves very low visitation. As such it forms a steep visitation gradient with Cabrillo 1. This site may occasionally be exposed to San Diego Bay water which is a potential source of pollution. There is heavy boat traffic offshore coming and going from San Diego Bay. This gently sloping site consists of moderately uneven terrain, containing few cracks and folds.
