For a fun day outside with the kids, put this beach on your list of musts.
A beach park with a lot of activities.
If you're traveling with little ones or you like to surf (or just splash around in) the waves yourself, you'll find a full menu of options at the the Prado Beach Park, a man-made strand created in the 1970s with the idea of taking advantage of the mistral wind which buffets the coast. This of course makes it a key local surf spot, so you can rent a wetsuit and a board and catch some waves, or just take advantage of the hammocks, beach bars, water toys, Jet Skis, and so forth. Weather permitting, at night you can also hang out for open-air concerts. Keep in mind that this is a stony beach, so if you're looking for something a little sandier, you might want to head to Pointe Rouge, also near Marseille and especially popular among families with small children.
