I had a swim in the ocean last time I visited. The «beach» were tiny, I would guess 15m wide?
Nice to take a dip and feel the waves, no problem. Not sure if we are talking about the same thing, huge place.
They charge a reasonable entrance fee for visitors, very good pools/water parks.
There were at least a couple of violent issues of confrontation of the SOV security guards and Dominicans who came by boat to party there.
