Ya'i Heki' Regional Indian Museum


Ya'i Heki' (pronounced yahee ehkey) is translated from the Cahuilla language meaning "Home of the Wind". This museum is one of a series of regional museums funded by the State of California.

The museum is open to the public on Saturday and Sunday from 10:00 a.m. until 4:00 p.m. and Fridays from 10:00 a.m. until 2:00 p.m.  The museum provides a comprehensive interpretation of Native American history, the cultures of the various native tribes throughout the southern California region and an educational experience into the cultures of the Indigenous peoples of inland southern California.  Additionally, we feature displays on the local flora and fauna of the southern California bio-region, and early Spanish explorers.  We invite you to come in a explore!  

We invite you to become involved in this important cultural resource on your next visit to Lake Perris.  You can view the park's calendar either below on this page, or here.  

Engaging School Tours are available by appointment Thursdays and Fridays.  Our standard school tours have 3 parts: Regional Indian Museum Tour, a Native American Craft Making or Game Activity, and a Natural Sciences component.  Special topics may be available upon request.
