Cabo Largo is the best private beach club in Mar del Plata. Or, it's at least the best one that I was able to find. This place literally has everything that you need. As soon as you enter, there is a huge parking lot for your car. The first section has a large full service restaurant with views of the beach. There are also large beds for suntanning.
If you prefer to be closer to the water, they also have a huge section of small tents for rent, where you can leave all your stuff. The beach is very big with plenty of space for everyone to lay down and sunbathe. There's volleyball nets as well.
And if you don't want to eat at the restaurant at the entrance, there are many other food options. There's a bar on the beach, and several outdoor stalls spread out offering pastries, smoothies, sandwiches, and snacks. read more
