A short loop our of the small village of Port Costa. This trail offers views of the Carquinez Shoreline, and is a popular spot for spotting birds.

We started from the Nejedly Staging Area in Martinez, hike along the Carquinez Scenic Drive and the George Miller Trail, and continued to Port Costa Staging Area and return. This is an out and back hike along paved walkways/roads for a total of 7+ miles, and a total ascent of 575 feet.

nice ocean breeze not too difficult to bike, and some great views of Vallejo and bridges.
