The reserve covers an area of approximately 3,000 acres and is home to a diverse range of plant and animal species. There are many good reasons to visit Bair Island, including its beautiful scenery, abundant wildlife, and opportunities for outdoor recreation.
One of the main points of interest in Bair Island is its extensive wetlands, which provide vital habitat for many bird species, including endangered ones like the California clapper rail and the salt marsh harvest mouse. Visitors can also see a variety of other animals, such as harbor seals, sea otters, and even sharks.
In addition to its natural beauty, Bair Island has a rich history. The area was once used for salt production, and there are still remnants of the salt flats that once covered the islands. Visitors can also learn about the area's role in the development of the local fishing and shipping industries.
