Upper Newport Bay

Upper Newport Bay in Newport Beach is an estuary – a place where fresh and salt water meet and mix. It is one of only a few remaining coastal estuaries in Southern California and is home to nearly 200 species of birds, including several endangered species, as well as numerous mammals, fish, and native plants. The bay is an important stopover for migrating waterfowl and shorebirds on the Pacific Flyway – up to 30,000 birds can be seen daily during the winter months. The bay is renowned for both its beauty and outstanding outdoor activities that include bird-watching, jogging, bicycling, hiking and kayaking.
