Lake Perris State Recreational Area and Ya'i Heki' Regional Indian Museum [CA]
Two hundred years ago, when the first overland immigrants from Mexico passed through this area under the leadership of Captain Juan Bautista de Anza, they saw a fertile valley, well watered by springs and even a small river that ran into San Jacinto Lake. Now, the river has been diverted and several of the springs have disappeared. The Regional Indian Museum, located in the park, offers a look into the lives of the native peoples who lived in the area before the Spanish habitation.
The museum offers tours and exhibits.
