There was another volleyball area and net that I recall that was near the old Waikiki Beach Bar. It was set a back a bit on he sand. But, who knows what became of that. Playing volleyball on the beaches at St. Martin isn't like the organized games that the resorts in Jamaica or Mexico typically have. You'll have to recruit a few others to join in, but you shouldn't have too much trouble doing so. It's a great way to get exercise on the beach.
