This historic cupola-topped structure, a California Historical Landmark, was built in 1906 as a bathhouse for swimmers in their ankle-length bathing costumes. Later, during the Big Band era, dancers rocked the Pavilion doing the Balboa Hop. Now it serves as the terminal for Catalina Island passenger service, harbor and whale-watching cruises, and fishing charters. The surrounding boardwalk is the Balboa Fun Zone (tel. 949/673-0408; www.thebalboafunzone.com), a collection of carnival rides, game arcades, and vendors of hot dogs and cotton candy. For Newport Harbor or Catalina cruise information, call tel. 949/673-5245; for sport fishing and whale-watching, call tel. 949/673-1434.
