Sostomo Trail

Embark on the Sostomo, Rising Sun, and Deer Valley Loop Trail for a diverse hiking experience in the Santa Monica Mountains. This moderate route spans 6.8 miles (11.0 km) and involves a substantial 1498 feet (456 metres) of elevation gain, typically taking around 3 hours and 29 minutes to complete. You will traverse varied terrain, from winding paths through lush green hills to more exposed sections offering expansive views. Keep an eye out for the Deer Valley Loop Trail Viewpoint, which provides an exceptional vantage point over Solstice Canyon and the vast Pacific Ocean, where you might even spot Catalina Island on a clear day.

Planning your visit requires acknowledging the trail's moderate to difficult rating, which means you should have good fitness for its steep inclines and declines. Be prepared for exposed sections, especially along the Rising Sun and Deer Valley trails, which can become quite intense during hot weather. The trail is suitable for both horseback riding and for bringing your dog, provided they are kept on a leash throughout your journey.

Beyond the natural beauty, the Sostomo Trail offers a glimpse into the area's past with intriguing historical ruins. You will encounter remnants like burnt chimneys and stone walls, which stand as silent witnesses to past wildfires that have shaped this landscape. These features add a unique historical layer to your hike, distinguishing it from other trails in the region.
