According to web site "At this time bicycles and dogs are allowed only in the Causeway which is between Interstate 80 and the Railroad tracks." http://yolobasin.org/yolobypasswildlifearea/ "The north side of the preserve, between Interstate 80 and the railroad tracks down which Amtrak trains whiz every couple of hours, is open to dogs and their people (see map; look for dog symbol between highway and railroad tracks)." https://dogtrekker.com/yp/yolo-bypass-wildlife-area-davis-95618
Dogs are not allowed outside of vehicles on the actual wildlife area.
I was there today. The sign says "no dogs".
