The Suisun Marsh is the largest brackish tidal marsh in the western United States. Named after the Suisune Tribe of the area, the 116,000-acre tidal wetlands are home to Grizzly Island, a large waterfowl hunting preserve, and the Rush Ranch Wildlife Preserve and Educational Center. The wetlands are also home to countless bird, fish, and river otter species. Various agricultural and development projects over the last century damaged these wetlands, but recent rehabilitation projects have begun to restore the Suisun Marsh to it's former beauty.
This very short 1.5-mile loop climbs 100 feet to the top of Suisun Hill, giving 360-degree views of the marshlands as well as Fairfield, Suisun City, and the massive military jets taking off and landing at the nearby Travis Air Force Base. Park along the road opposite the Rush Ranch entrance and enter through the gate. Follow the trail signs until you reach the intersection of the loop. Embark in either direction and join the small herd of cows as you continue along the loop. Cow dung and ground squirrel holes litter the trail, so watch your footing. Once you reach the top of the hill, take a break on the benches that were donated by the Boy Scouts before you return to your car.
