Located in the cliffs and canyons of the Santa Monica Mountains, Topanga State Park features 36 miles of trails through open grassland, live oaks and spectacular views of the Pacific Ocean. The park is located entirely within the Los Angeles city limits and is considered the worlds largest wildland within the boundaries of a major city. Excellent recreational opportunities for hikers as well as mountain bikers (restricted to fire roads) and equestrians. The park is bound on the south by Pacific Palisades and Brentwood, on the west by Topanga Canyon, and on the east by Rustic Canyon. Numerous geologic formations can be found in the park, including earthquake faults, marine fossils, volcanic intrusions, and a wide variety of sedimentary formations. Dogs are not allowed on the park trails, fire roads, or in the back country.

I would rate the difficulty at the top end of the moderate level, it's definitely not hard or difficult.
