* The majority of the exterior shots were filmed at the "Big Sky Movie Ranch" in Simi Valley, California.** This location served as the town of Walnut Grove and included the iconic Ingalls homestead.
* Other locations used included:
* The Paramount Ranch in Agoura Hills, California (for the town square and other scenes)
* Various locations around Los Angeles County (for landscapes and specific settings)
* The Vasquez Rocks Natural Area Park in California (for the "Little House" opening credits)
It's important to note that the show was not filmed in the actual historical locations described in Laura Ingalls Wilder's books. The series was set in Kansas, Minnesota, and Dakota Territory, but filming took place primarily in California for logistical reasons.
