Simi Valley

Simi Valley is a city in Ventura County, California, nestled between the Santa Susana Mountains and the Simi Hills. The area spreads across flat valleys and gentle slopes with residential neighborhoods, parks, and commercial districts.

The Chumash lived in the region for centuries before Spanish settlers established the Rancho Simi land grant in 1795. In the 20th century, the area transformed from agricultural land into a modern suburb.

The city takes its name from Shimiyi, a Chumash word for the cloud formations above the valley. Many street names and parks today recall this early settlement by indigenous communities.

The city sits about 40 miles from Los Angeles and is easily accessible via the Ronald Reagan Freeway. Many visitors combine a stay here with trips to the San Fernando Valley or surrounding mountains.

The Ronald Reagan Presidential Library houses sections of the Berlin Wall and the Air Force One that transported the president. Visitors can walk through recreated White House rooms.
