Llano Seco Sign
Entrance sign, restroom, interpretive display and viewing platform (Robin Sigel)


The Llano Seco Unit of the Sacramento National Wildlife Refuge Complex is a winter wetland area about 10 to 14 miles south of Chico, depending on your chosen route to get there. This is one of the best public viewing locations, near Chico, for viewing water birds in the fall, winter and early spring months. It is also a great location to pickup some of the migrating shorebirds in the springtime as they head North. Llano Seco has two viewing platforms with handicap access available to the viewing platform closest to the entrance. There is a restroom and a interpretive kiosk at the parking lot. The walk to the back viewing platform is about a half mile on a gravel road.

Most if not all the ponds are dry during the summer months. The filling of the ponds usually begins in October (Back ponds first) and they are full by middle to late November. Llano Seco has an abundance of Pintail Ducks in the winter. American Widgeon are also very Common here. At least one Eurasian Widgeon seems to spend the winter on the front pond and often times, more than one can be spotted. Green-winged Teal seem to like the shallow water at the south-west back corner of the font pond although, on a good day, they may be seen along side the islands closer to the front viewing platform. Osprey may be seen here fishing in the spring as the ponds begin to dry up. Check below for a full list of birds found at this site.

Check on the Altacal Audubon web site for any upcoming field trips to this area.
