The Upper Newport Bay (located in Newport Beach Ca.) is a large coastal wetland (an estuary) in Southern California and a major stopover for birds on the Pacific Flyway. Dozens of species, including endangered ones, can be observed here. Upper Newport Bay Nature Preserve and Ecological Reserve represent approximately 1,000 acres (4 km2) of open space. The Upper Newport Bay was purchased by the state in 1975 for its Fish and Wildlife Department’s Ecological Reserve System. In 1985 the upper west bluffs and lands surrounding the bay became part of a county regional park. This beautiful setting offers outdoor activities such as bird-watching, jogging, bicycling, hiking, and kayaking. The Peter and Mary Muth Interpretive Center, located at 2301 University Drive, is open to the public Tuesday through Sunday from 10:00 AM to 4:00 PM. An organization known as theNewport Bay Conservancy (NBC) provides volunteers to answer your questions and guide you to the various activities. NBC naturalists volunteers offer numerous educational opportunities including bird and plant walks and guided kayak tours.
Upper Newport Bay is connected to the ocean through Newport Beach harbor.
