Long Bay Beach is quite atypical for a St. Maarten/St. Martin beach. Most of the island's beachs are beautiful, sometimes a little crowed, and offer amenities such as snack bars, and chaisse lounges you can tip an attendent to set up for you. Long Bay is beautiful, about a mile and a half long with one resort at one end of the beach, sparsely populated, and you have to carry in anything you want to eat, drink, and sit on. Because it is undeveloped you get a good idea of the island's natural beauty, with many large rock formations along the shore. The scarcity of other people means you can have a pretty good expanse of beach all to yourself. My wife and I always found it well worth the effort to carry in a cooler and some beach towels. The water is remarkably clear, and the surf is mild to moderate, just about perfect for bobbing with the waves. We've been to St. Maarten/St. Martin three times, and we love so much about the island: the food, the shopping, the scenery, the Cuban cigars, (okay, the shopping's for her, the cigars are for me, the food and scenery for both). We've tried many of the beaches there, but we always end up spending the lion's share of our beach time at Long Bay. If you want the amenities, and lots people to watch, it's not for you; but if you really like to get away from it all, Long Bay Beach is perfect.
