The pre-colonial history of this area is divided into an early (prior to circa 900 BCE) and a late period. The period of habitation is from around 850 CE to 1790 CE. The peoples believed to have occupied this site are the Kumeyaay (formerly known as Diegueno/Ipai), although there are strong traces of Luiseño as well. During the late period, the Westwood Valley complex was a village located along an intermittent stream bed. This village was likely known to the Kumeyaay as Sinyau-Pichkara.{{Cite web |title=Sociopolitical Aspects of the 1775 Revolt at Mission San Diego de Alcala |url=https://sandiegohistory.org/journal/1997/july/missionrevoltimages/ |url-status=live |archive-url=https://web.archive.org/web/20200814155541/https://sandiegohistory.org/journal/1997/july/missionrevoltimages/ |archive-date=2020-08-14 |access-date=2020-08-30 |website=San Diego History Center {{!}} San Diego, CA {{!}} Our City, Our Story |language=en-US}} The area the village occupied is now under the western section of Ranch Bernardo near Duenda and Poblado Roads.

In the 1960s, Rancho Bernardo was annexed by San Diego. The area was developed by AVCO Community Developers until their involvement ceased in 1984.{{Cite web |title=History - Rancho Bernardo Historical Society |url=http://www.rbhistoricalsociety.org/history |url-status=live |archive-url=https://web.archive.org/web/20161018201958/http://www.rbhistoricalsociety.org/history |archive-date=2016-10-18 |access-date=2016-10-14}} The Rancho Bernardo Inn opened at the center of the development in 1963.{{cite web | url=https://www.historichotels.org/us/hotels-resorts/rancho-bernardo-inn/history.php | title=Historic Hotels of America }}

On October 22, 2007, the Witch Creek Fire burned through Rancho Bernardo and several other populous areas of San Diego County, destroying hundreds of homes, and completely destroying several entire neighborhoods, particularly ones that firefighters had trouble accessing due to rugged terrain and rapidly advancing flames pushed by strong Santa Ana winds. The highly unpredictable flames pushed into the northeast section of Poway during the day, prompting evacuation of Palomar-Pomerado Hospital. The neighborhoods of the Trails, Montelena and Westwood were the main areas hit in Rancho Bernardo.
