Malibu Creek State Park. I am a docent at MCSP and it is a great place to visit. The Malibu Creek Docents website is http://malibucreekdocents.org. This mailing list has been created so that interested parties can talk about their experiences at the park, share fun places to go, etc. Malibu Creek State Park is located between Calabasas, California and Malibu, California, in the mid-portion of the Santa Monica Mountains, and in the southwestern part of Los Angeles County.
