In my opinion this is the best planespotting point anywhere on earth! One can see heavies like the 747 & A340 flying low over your head seconds before they touchdown at the Princess Juliana airport.
There is a beachside pub called Sunset Beach bar which has a vertical surfboard on which are listed the various arrivals of the day and their timings for people's benefit. This is a favorite with planespotters around the world.
One more interesting trivia about the Sunset Beach bar is a notice stating - "topless women drink free here"
