Cal. Pub. Resources Code § 5003.1
The Legislature finds and declares that it is in the public interest to permit hunting, fishing, swimming, trails, camping, campsites, and rental vacation cabins in certain state recreation areas, or portions thereof, when it is found by the State Park and Recreation Commission that multiple use of state recreation areas would not threaten the safety and welfare of other state recreation area users. Hunting shall not be permitted in any unit now in the state park system and officially opened to the public on or before June 1, 1961, or in any unit hereafter acquired and designated by the commission as a state park, state marine reserve, state marine park, state reserve, state marine conservation area, or state marine cultural preservation area, and may only be permitted in new recreational areas and state marine recreational management areas that are developed for that use.
Whenever hunting or fishing is permitted in a state recreation area or state marine recreational management area, and whenever fishing is permitted in a state park, state marine park, state marine cultural preservation area, or state marine conservation area, the Department of Fish and Game shall enforce hunting and fishing laws and regulations as it does elsewhere in the state.
