Malibu Creek State Park, 25 miles from downtown Los Angeles, is located in the heart of the Santa Monica Mountains. The 10 km course is a good introduction to trail running in a beautiful setting where films like M*A*S*H, Planet of the Apes and Pleasantville were shot. For a refreshing river crossing and views of the ocean, go for the 25 km loop which also brings you up the mountain range for some amazing rock formations. Can't get enough? There is always the 50 km!
