Upper Newport Bay

This 752-acre estuary, intertidal mudflat and salt marsh wildlife reserve is a vibrant ecosystem home to many different species from sea slugs to thousands of migratory shorebirds and waterfowl. So bring your binoculars! There are hiking, biking and riding trails, please stay on established trails as there are also endangered plant species in this fragile habitat. North Star Beach has a small-craft launch as well as kayak rentals, fishing, showers and wheelchair accessible restrooms. Parking is free. The Peter and Mary Muth Interpretive Center has a unique earth sheltered architecture that keeps it hidden from view at street level, while simultaneously creating a feast for the eye once visitors reach the main entrance, it is located at 2301 University Drive at the corner of Irvine Ave. The Department of Fish and Game runs the Newport Back Bay Science Center, on Shellmaker Island, for educational field trip and events. Reminders: There is a 3-day rain advisory after each rain storm, use caution as bacteria levels can increase during this period. The County Environmental Health staff advises swimmers that levels of bacteria can rise significantly in ocean and bay waters adjacent to storm drains, creeks and rivers. Swimmers should avoid coastal waters impacted by discharging storm drains creeks and rivers, and beach users should avoid contact with any runoff on the beach during dry or wet weather conditions. As an extra precaution remain 500 ft away on either side from any outfalls.
