9 Best Sights in St. Martin, St. Martin and St. Maarten

This beautiful beach seems to have it all—champagne-color sand, an underwater marine reserve, a variety of water sports, and trendy beach clubs. Topless bathing is allowed along the whole stretch of it (there was once even a nudist resort on its southern end), so cameras are a no-no. To get here from Marigot, take the main road north past Grand Case, and watch for the left turn. There's parking and toilets.

A protected nature reserve, this kid-friendly island is a five-minute ferry ride from French Cul de Sac (about €12 per person round-trip). The ferry runs every half hour from midmorning until 4 pm. The water is clear and shallow, and the shore is sheltered. You can swim and snorkel (equipment rental is available) between both coasts of this pencil-shape speck in the ocean. The two restaurants, Karibuni and Yellow Beach, both offer great service, with cocktail tables in the water. Chairs and umbrellas can be rented for about €25 for two. The island can be busy on Sunday.

Not many people know about this romantic, hidden, clothing-optional gem with powdery sand, good snorkeling, and stunning views of Anguilla. Access is via the rather rutted dead-end road to Baie des Péres (Friar's Bay), where, from the northernmost beach bar, it's an easy, 10- to 15-minute easy hike to this beach.

This skinny stripe of a beach borders the culinary village of Grand Case, where you can still see examples of old-style gingerbread architecture. The sea is usually quite calm, and there are tons of fun lunch options—from bistros to beachside grills (called lolos). Several restaurants rent chairs and umbrellas; some include their use for lunch patrons. The main street (aka Restaurant Row) has some of the island's best restaurants, as well as places to shop for beach necessities and fashions, as well as handicrafts.

This quiet, occasionally rocky cove close to Marigot has beach grills and bars with chaises and umbrellas, usually calm waters, and a lovely view of Anguilla. Open daily for lunch and (weather permitting) dinner, the chic 978 Beach Lounge has a cool, jazzy vibe. It's the best place to be during the full moon, with music, dancing, and a bonfire, but you can get lunch, beach chairs, and umbrellas anytime. Another option is Friar's Bay Beach Café, a French bistro on the sand that's open from breakfast to sunset. To reach the beach, take National Road 7 from Marigot, go toward Grand Case to the Morne Valois hill, and turn left on the dead-end road at the sign. Note the last 200 yards of road to the beach is dirt and quite bumpy.

Although it's a great place for a romantic walk and is home to the luxurious Belmond La Samanna hotel, this lengthy beach has no facilities, vendors, or shade of its own. It's also on the leeward, less breezy side of the island, and getting here isn't as easy as it once was—access is via the National Road 7 south of Marigot, and you must pass through the security checkpoint of the exclusive Terres Basses (French Lowlands) residential community.

This gorgeous beach and its salt ponds make up a nature preserve, and the area is widely thought to have the island's best snorkeling. You can swim the crystal waters along the point and explore a swim-through cave, but beware: the water can be rough. There's a sign and a right turn after you leave Baie Nettlé.

A coral reef borders this quiet, naturally protected beach 4 km (3 miles) northeast of Orléans and part of the French side's nature reserve. The water is calm, clear, and quite shallow, so it's a paradise for young kids. Kiteboarders and windsurfers like the trade winds at the far end of the beach and will find the beach satisfactory if they don't need those "services." On Sunday, there still may be some groups picnicking and partying, but during the week Le Galion is a rather desolate place better avoided.
