The Tule Elk State Natural Reserve protects a small herd of tule elk, once in danger of extinction. In the 1800s, the vast herds of tule elk were greatly reduced in number by hunting and loss of habitat.

In 1874, cattleman Henry Miller began efforts to save them. At that time few tule elk remained. In 1932, the herd was given permanent protection on the land now known as the Tule Elk State Natural Reserve.

Elk from the reserve have been successfully transplanted to other areas in California. Today approximately 5,700 tule elk are again roaming the foothills and grasslands of California.

The tule elk are most active from late summer through early autumn. Visitors are encouraged to bring binoculars for better viewing.

The park has a picnic area that offers an excellent opportunity to observe birds of the San Joaquin Valley. Interpretive exhibits may be viewed to the south and east of the comfort station.
