Lake Forest CA was actually called El Toro for much of its history. In fact, it spent over 100 years under this name before incorporating as Lake Forest CA in 1991. The name comes from the two man-made lakes that now anchor the community. The city is known as a very safe community and contains many master-planned developments with nice new homes. To outsiders, the most notable feature of Lake Forest CA is the mega church Saddleback Church which is the 8th largest in the country.
