Come here toward the end of a sunny day in winter for excellent birding and beautiful light. This is a nice stroll past three distinct marsh habitats in Coyote Hills Regional Park. You start out near the main freshwater marsh at the visitor center. On a sunny day in January, we saw lots of birds here, northern shovelers mostly. Some nice folks with huge camera lenses were shooting photos nearby as well (like this amazing ibis shot). We headed out on a level fire road trail past another marsh full of pintails, gulls, and a few herons and egrets. This makes a nice link to the Alameda Creek trail, which would be a perfect bike ride down from Fremont proper. We looped around past salt ponds full of other sea ducks and great views, back over a saddle in the hills to the visitor center.
