Upper Newport Bay


One of only a few remaining estuaries in southern California, Upper Newport Bay is a tranquil setting where fresh and saltwater meet and mix. Upper Newport Bay Nature Preserve and Ecological Reserve represent approximately 1,000 acres of open space. It is the home of nearly 200 species of birds, including several endangered species, as well as numerous varieties of mammals, fish, and native plants. The bay is an important stopover for migrating birds on the Pacific Flyway and up to 30,000 birds can be seen on any day during the winter months. Six rare endangered species can be found in this habitat including: the Light Footed Clapper Rail, Brown Pelican, Belding’s Savannah Sparrow, Black Rail, Peregrine Falcon and California Least Tern. The bay is also home to one endangered plant species – Saltmarsh Bird’s Beak. Activities: Kayaking (5.8 miles), Hiking (3.2 mile loop)
