Wilderness Landscape & Natural Heritage
Upper Newport Bay Nature Preserve is a 1,000-acre coastal wetland located in Orange County, California. It serves as one of the largest remaining natural estuaries in Southern California, where freshwater from the Santa Ana River mixes with saltwater from the Pacific Ocean. The preserve features mudflats, salt marshes, and upland coastal sage scrub habitats that support a variety of plant and animal species. It is designated as an Ecological Reserve and managed by the California Department of Fish and Wildlife, emphasizing conservation and habitat restoration. Migratory birds such as herons, egrets, and the California least tern rely on this area for resting and breeding, making the preserve a hotspot for birdwatchers and wildlife enthusiasts. The preserve's trails meander through these habitats, offering visitors accessible hiking and biking routes. Kayaking and paddle sports on the calm estuary waters provide a unique perspective to experience the diverse aquatic life. The historic Peter and Mary Muth Interpretive Center serves as an educational hub with exhibits about the bay's ecosystem, conservation efforts, and species found within the preserve. Located near Costa Mesa and Newport Beach, the preserve offers a tranquil natural escape from the surrounding urban environment and is popular among families, photographers, and nature lovers.
