The park was established January 1994 after a five-year planning process was implemented to address long-standing conflicts between preservationist, resource extraction and First Nations interests.

Chief Roger William of the Xeni Gwet’in (Nemiah Indian Band) was very involved in the planning process and negotiations with the provincial government.

The park aims to protect black bear, mule deer, moose, mountain goat, cougar, and beaver.

Ecologically sensitive animal populations found in the area include California bighorn sheep, grizzly bear, fisher, wolverine, bald eagle, and amphibian species.

The following recreational activities are encouraged: camping, picnicking, hiking, mountaineering, swimming, kayaking, horseback riding expeditions, hunting trips and flyfishing.
