This 90-minute, behind-the-scenes hiking tour takes visitors into Younger Lagoon Reserve adjacent to the Seymour Marine Discovery Center. Part of the University of California Natural Reserve System, Younger Lagoon Reserve contains diverse coastal habitats and is home to birds of prey, migrating sea birds, bobcats, and other wildlife. Come and see what scientists are doing to track local mammals, restore native habitats, and learn about the workings of one of California’s rare coastal lagoons. A tour is offered on selected Thursdays and Saturdays of each month beginning at 10:30 AM.
