Offering 360-degree views that extend from San Francisco to the Santa Cruz Mountains, this park contains an extensive brackish marsh, habitat for waterfowl and shorebirds.
Great short hike that takes you up to the top with great views of the entire South Bay. There are benches on the hill to sit down and enjoy the view. I warmed up with the Lizard Rock Trail before doing Red Hill Loop to get about 2.5 miles total.
