This is one of the most famous ports in the world, having been a location in many movies namely the…read moreFrench Connection (which I haven't seen yet). This port opened in the 6th century BC so it's been in existence a long time. It's lined with numerous boats and ferries as is many other port cities along the French coast/Mediterranean. Also, there are many seafood places that line the port itself that are a little pricey and are possibly Michellin/Zagat rated. In other words, a lot of sit-down places that take forever to eat. If you're in a hurry or don't want to spend a lot of money, you're better off walking on the adjacent street. There are lot of kebab places and other stuff that are much more affordable. This is the most populous area in Marseille and it was packed even in the winter season. Offices for Hop on, hop off are located around the port while the official tourism office is on the street leading up to the port. It's really a beautiful area. It's got a ferris wheel/other carnival like stuff for the kids and there were holiday shops lined up under the wheel as well.
It's a must see if you're in Marseille due to its history and prominence and I highly recommend going around and checking out the scenery for yourself!
