The trail starts at Chumash Park and flanks the western side of Rocky Peak (see https://www.yelp.com/biz/rocky-peak-park-simi-valley). The Chumash trail is not near the casino (and before you call me racist, the first listing on Google for Chumash is the casino not the tribe). Be kind to the homeowners and don't park on the street but the many open spaces in Chumash Park.
A real trail and not a firebreak road, the ascent was very evenly graded. The footing started with clay before turning into smoothly round rocks that fill Rocky Peak Park. For those wanting a leisurely walk, three park benches exist along the lower section with views of Simi Valley. One of the better views along the trail is marked with a black graffiti X and smiley face - clearly marking the spot of someone's happy place. Ground protrusions are marked with flame retardant red paint for mountain bikers. The Chumash Trail ends at a junction with Rocky Peak Rd. The trail is 5.2 miles roundtrip with a 1100' elevation gain. read more
