Trail shared by Ryan W

A great loop and an alternative to the Terri Peak Summit out-and-back.

I discovered this alternate when the Terri Peak Trailhead parking lot was closed. The ranger informed me that I should park at horse camp and use the spur trail as access from the lot. It is a nice change to see different scenery on the way back and is only 0.5 mile longer.

Need to Know

When open, I recommend stopping at the Ya'i Heki' Regional Indian Museum. The cost is free. Contact Lake Perris State Park for hours of operation.

Runner Notes

West side descent is very steep and sometimes hard to follow the trail. Wear good footwear and watch your footing.


Starting from the horse camp parking, head north to connect with the Terri Peak Trail. Like the Terri Peak Summit run, this route uses the same directions to the summit itself. However, instead of heading back the way you came after reaching the top, you'll continue down the backside of Terri Peak Trail until you reach the Ya'i Heki' Regional Indian Museum.

From here, follow the road for less than 0.25 mile to the Lake Perris Path - West, which is just south of the paved road and is accessed near Sail Cove. This equestrian trail is not very busy and is well-packed sand. It has nothing by the way of big rocks, roots, etc.

This trail gives beautiful views of the lake through trees and grasslands as it gently climbs back to Horse Camp. The equestrian trail is quite scenic. It follows the lake through tall grasses for spectacular views of the park. Sandy footing makes it easy.

Many people do not even know this trail exists so it is somewhat secluded. There is even some shade from various trees such as eucalyptus. Maybe you'll even get lucky towards sunset and spot a deer or coyote.

Flora & Fauna

Typical California sagebrush and grasses. Trail becomes very green and beautiful during winter-springtime.

History & Background

Ya'i Heki' (pronounced yahee ehkey) is translated from the Cahuilla language meaning "Home of the Wind".
