Cost: €10 per person. For me, it's not worth it. The beach is small and everyone is close by.
There are much nicer beaches, and they're free.
There's a fee to enter the beach, €10 per person. You have to arrive early in the morning, around 7:30, to get in. You park your car and then walk down to the beach for five minutes. We were there in early September. Arriving at 10:00, we already knew we wouldn't be able to get in at that time. They advised us to arrive at 2:00 PM. Who knows, some cars might leave the beach, which is highly unlikely. In fact, we returned at 6:30 PM, when entry is free. The beach is worth it; it's beautiful, nestled between two seas: one shallow, sandy, and crystalline, and the other rocky, deep, blue. There's very little space, given the two beach clubs that take up almost all of the little beach that remains. I recommend visiting in the morning; it's really worth it.
