A pleasant, easy loop -- though be prepared for lots of wind and sun. Not crowded even on Memorial Day. Some cool bird life. A good place to get moving -- some cool views though it can be monotonous for stretches. I enjoyed it. Seemed like it would be a great little running or cycling loop. (This entry may be a duplicate with the Don Edwards Wildlife Refuge listing by mistake.) The tiny loop by the pump house is also worth doing -- egrets and cormorants over there.
