Long beach is... well pretty long. The combination of one of the longest stretches of continuous beach in St Martin and few visitors makes it easy to stake your own claim to a portion of the beach. I went there on an extremely nice day and there was hardly anyone there. We were probably at least 50 yards from another beach-goer. I am not sure if this is true, but I was told the currents can be quite strong at that beach so we didnt do much swimming - just waded out to about chest level. It was very relaxing and quiet which made it an excellent place to read and then nap.
