Coldwater Canyon (Spanish: Cañada de las Aguas Frias) is a canyon running perpendicular to and over the central Santa Monica Mountains, in Los Angeles County, California, United States.
A section of the canyon south of Mulholland Drive is also a neighborhood in the Beverly Crest Neighborhood Council of the City of Los Angeles. Hidden Valley is the area "just below Mulholland on the west side of Coldwater" that used to be Myrna Loy's estate.[1]
