The Llano Seco Unit is part of the Steve Thompson North Central Valley Wildlife Management Area, and is situated about 10 miles southwest of the city of Chico. The Unit consists of 1,732 acres, comprised primarily of wetlands and grasslands with some riparian habitats. The Unit supports large populations of wintering waterfowl, as well as other species such as: bald eagle, mountain lion, bobcat, State-listed as threatened greater sandhill cranes, Swainson's hawk, federally threatened giant garter snakes and valley elderberry longhorn beetle, federally endangered vernal pool tadpole shrimp and vernal pool fairy shrimp, and species of concern California linderiella and Ferris's milk-vetch.
The Llano Seco Unit consists of two distinct areas: the non-public use Sanctuary I (967 acres) and the public-use Sanctuary II (765 acres). On Sanctuary II, visitors can engage in wildlife observation, photography, environmental education and interpretation.
There is a 1/2-mile walking trail and two observation platforms open to the public from one hour before sunrise to one hour after sunset.
