From East Bay Regional Park District:

CONTRA LOMA REGIONAL PARK - Follow the E. Shore Trail to the right of the boat ramp, where we'll be stationed with a spotting scope on the path zooming in on the many different types of birds that call this lake home!

We recommend parking at the Fredrickson Lane Staging Area for easy access.
