While spending a couple days at the Long Beach Harbor, we found that a cheap and fun thing to do is to take the Aqua Link, a motorized catamaran to Belmont Pier and then down to Alimitos Bay. For $5 you can take the ride which starts at the Pike area and goes down to Alimitos Bay and $5 for the return. The coastline is beautiful. There are plenty of restaurants and shops in the Long Beach Harbor area as well as in Alimitos Bay. On the return, the boat goes right up along side of the Queen Mary and the Russian submarine. You can get off the boat at any stop and then catch the next boat to continue your trip. This is a great way to see the harbor as well as going someplace else for a fun inexpensive experience.
