Los Peñasquitos (meaning little cliffs) Canyon Preserve lies between Rancho Peñasquitos and Sorrento Hills to the north and Mira Mesa to the south. It stretches approximately 7 miles from the Interstates 5 and 805 merge to just east of Interstate 15. It encompasses some 4,000 acres of both Peñasquitos and Lopez Canyons. The Preserve is jointly owned and administered by the City and County of San Diego.
Los Peñasquitos Canyon Preserve attracts people with its natural beauty and abundant natural resources -- both today and in the past. Native American history within the Preserve dates back as far as 7,000 years ago.
Remains of the prehistoric culture can still be found. More recently the area was part of the first Mexican land grant in San Diego County. The historic Santa Maria de Los Peñasquitos Adobe (ca. 1823) operated by the County of San Diego (located at the east end of the Preserve off Black Mountain Road on Canyonside Park Driveway), has been restored and tours are available for school groups and the public.
For more information, please call the County Park Rangers at (858) 484-7504.
The ruins of another Adobe, the El Cuervo (ca. 1857), sit at the west end of the Preserve.
Los Peñasquitos Canyon and its tributary, Lopez Canyon, are characterized by varied natural resources. Evidence of the rich biodiversity of the canyon include over 500 plant species, more than 175 types of birds, and a great variety of reptiles, amphibians and mammals. Many of these species are rare or endangered and are protected within the Preserve.
For safety and the protection of the park's resources, please adhere to Park Rules & Regulations.
Many different geologic formations and soil types make up the steep slopes, riparian stream corridors, flat mesa tops and grassy hillsides of the Preserve. The varying terrains and soil types, in conjunction with continually flowing water, form more than 14 habitat types and support a diverse collection of flora and fauna.
The scenery of the canyon includes:
