The popular tours allow people to get an up-close and personal, behind-the-scenes look at the Port of Long Beach. Visitors get to see massive ships -- some larger than the Empire State Building -- and witness how $100 billion a year in trade gets loaded on and off ships.
Tours take place the first and third Saturdays of each month at 10 a.m. and the second and fourth Thursdays at 7 p.m.
The tours are very popular and usually fill up the first day of registration.
