There are 37 beaches on Sint Maarten/Saint Martin. The answer for you depends on your tastes and whether or not you want to see or object to seeing naked people or topless women.

In addition, I found this editorial comment somewhere:
Some like it hot, some like it shady, some like it quiet, some like to party
but no matter what type of beach you love to sink your toes into, there's a good chance this island has a beach just for you. Here are a few favorites:
<b>Best for Swimming</b>
Gentle surf, shade, refreshment stands and change facilities make <b>Mullet Bay Beach</b> a swimmer's dream. Good snorkeling, too. Tops optional.
<b>Best for Snorkeling</b>
Known for its spectacular sunrises, <b>Dawn Beach</b> is also the place for fish spotting. <b>Little Bay</b>, a popular meeting spot for locals, is another snorkeling favorite. Water sports also available. Facilities for both beaches are at nearby hotels.
<b>Best for Romance</b>
<b>Simpson Bay</b> features a mile-long beach ideal for leisurely strolls and romantic swims. Picturesque fishing village and refreshment facilities nearby. <b>Baie Longue</b>, the island's longest beach, offers pristine privacy. Keep your eyes open for visiting celebrities
this is their favorite haunt. No facilities. <b>Baie Rouge</b> is another idyllic spot with beautiful scenery, plenty of beach space and refreshment facilities. Look for Devil's Hole, an amazing anomaly of nature. Tops optional.
<b>Best for Food</b>
Granted, eating isn't really a best beach category, but <b>Grand Case</b> is a unique stretch of sand for the gourmet lover. Good swimming and scenery, but it's most famous for its incredible dining spots and on-the-beach chicken and ribs lolo fare.
<b>Best for Kids</b>
A virtual sea paradise, <b>Galion Beach</b> has shallow waters protected by a coral reef. It also offers boardsailing and windsurfing rentals and instruction. Full facilities. <b>Anse Marcel</b> is another terrific family beach with lots of shade, calm waters and nearby facilities. The delightful little island of <b>Isle Pinel</b>, just a 5-minute water taxi ride from French Cul de Sac, offers great snorkeling and lots of shallow water and protection from the pounding surf. Food and drinks available.
<b>Best for Scenery</b>
<b>Cupecoy</b> is the island's most breathtaking beach, with towering, craggy cliffs and sea-worn caverns. Cupecoy is constantly changing: sometimes there's sand, sometimes there isn't. No facilities. Clothing optional.
<b>Best for People Watching</b>
<b>Maho Beach</b>. It's great fun watching sunbathers lounging peacefully on the beach one second, then looking up at a 747 directly over them the next (the beach is just off the runway touchdown point of Juliana Airport). Those in the know park themselves out of the way on either side of the flight path. Spectacular photo ops. Facilities.
<b>Best for Bodysurfing</b>
Check out <b>Guana Bay</b>, a natural treasure with rugged beauty and great waves. Only a few minutes drive from Philipsburg. Limited facilities.
<b>Best of Everything</b>
Called the Riviera of the Caribbean, <b>Orient Bay</b> has it all. Every kind of water sport, including parasailing and jet skiing, tons of eateries and bars, live music, gorgeous scenery, you name it! The far end is a naturist retreat, but there is often nudity along the entire strip of beach.
