Chumash Trailhead

The Rocky Peak, Las Llajas, and Chumash Loop is a demanding jogging route that showcases the rugged beauty of the Santa Susana Mountains. You will traverse varied terrain, from the shaded oak groves and creek beds of Las Llajas Canyon to exposed, rocky fire roads and technical singletrack on the Chumash Trail.

This difficult 16.5 miles (26.5 km) loop involves a substantial 2979 feet (908 metres) of elevation gain, typically taking around 3 hours and 16 minutes to complete. Be sure to bring ample water, as much of the route, particularly the Rocky Peak Fire Road, offers little shade. The trail is popular with mountain bikers, so stay alert, and consider visiting in spring for the best wildflower displays.

Beyond the physical challenge, this trail is notable for its geological features, including "Fossil Point" with its ancient seashells, hinting at a past as a marine lagoon. The area is also a vital wildlife corridor, so you might spot deer or various birds. Historically, Las Llajas Canyon has seen use as an oil field, with old pumps still visible, adding a layer of historical intrigue to your run.

If you're seeking a challenging jogging experience with a big payoff in views, the Rocky Peak Trail loop from Santa Susana Pass State Historic Park delivers. This difficult 7.3-mile (11.7 km) route, which you can complete in about 1 hour and 24 minutes, takes you through a rugged, arid landscape dotted with spectacular sandstone boulders and unique rock formations.

The final push to the summit involves a strenuous scramble over boulders, making it a true test of endurance.

Planning your visit requires a bit of foresight due to the trail's exposed nature; there's very little shade along the route, so cooler days or early morning starts are highly recommended.
