The Port of Long Beach will once again host free harbor tours beginning in May, offering the public a chance to visit the sights and sounds of the nation’s largest seaport complex, port officials announced today.

The 90-minute narrated tours will teach riders about how the Port of Long Beach impacts local residents, regional and national economies, get close to some of the biggest ships in the world, learn about the port’s zero-emissions operations and take pictures of machinery and local marine life.

Registration online begins April 17 from 8 a.m. to 8 p.m. for the opportunity to receive a free harbor tour in May. The port uses an online lottery sign-up system for reservations.

Reservations will open on the third Monday of the month for tours the following month. The online reservation system provides a 12-hour window to register for an available tour the next month. A random drawing will select participants, who may reserve up to four seats each.   Tours are scheduled four times a month, twice at 10 a.m. Saturday mornings and twice at 6:30 p.m. on Wednesday evenings. Tours this year will beheld May through August.
