For hunting open and closed zones/units, please refer to the Hunting Map

To best appreciate this area, one needs to use a small boat or kayak and navigate the many sloughs that circulate through the interior of the marsh as most of the property is accessible by boat only. There are several launch areas located on the Napa River and one site on Hudeman Slough, however, please consult local tide tables for the best (and most safe) boating opportunities to tour the area. Also please be aware of waterfowl hunting activity during the months of October through January each year.
