Background: | |||
This salt marsh and upland fields are just a few miles from a major Bay Area freeway, but area feels isolated and the only city in sight is San Francisco, across the bay. The 3-mile hike to the wetland follows a road closed to vehicles and bordered by Tolay Creek and grassy fields. Northern harriers and white-tailed kites cross the skies above, while herons and egrets fish along the creek. Riparian vegetation shelters fox sparrows and western meadowlarks. The road ends at Tubbs Island, where a hiking loop explores the bay and salt marsh, with views of American white pelicans, canvasbacks, and scaups. Look here for long-legged shorebirds such as willits and godwits. Harbor seals haul out along the shore. Follow a second hiking loop inland to marshes and ponds favored by dabbling ducks, sandpipers, and black-neck stilts. | |||
