The Angeles, San Bernardino, Cleveland, and Los Padres National Forests are all closed until further notice. The Santa Monica Mountains National Recreation Area is also closed, although the visitor center in Thousand Oaks is still operational. Violators are subject to fines and imprisonment.

Not that you really want to be hiking in the smoky air, anyway.
