Little House on the Prairie was primarily filmed at Big Sky Ranch in Simi Valley, California. It served as the primary site for the majority of external shooting of the series, including Walnut Grove and the Ingalls home.
Big Sky Ranch is closed to the public and has been used to film many shows and movies over the years, including another Western, Gunsmoke, and Highway to Heaven, another Michael Landon TV series.
The majority of the set was destroyed during the filming of the episode The Last Farewell, where the townspeople destroy the town’s buildings so the new owners will not benefit from their hard work.
The area where filming occurred on Big Sky Ranch was destroyed by wildfires in 2003, including some of the set that remained standing and a replica Little House that was rebuilt on the site.
