Corriganville Park is a 246 acre park located in Simi Valley, CA.  At one time this area was used as a movie ranch.  Fires destroyed most of the western themed sets in the 1970s.  Today you can find remains of the stables and some other structures.  Many signs along the trail give you detailed descriptions of the surrounding scenery.
