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.
