Baie Longue
The island's longest stretch of untouched white sand
Why Go
Baie Longue lives up to its name. This sweeping crescent of white sand extends further than any other beach on St. Martin, curving along the Terres Basses peninsula where turquoise water meets a coastline that still feels genuinely wild. No beach bars, no lounger rentals, no DJ booths — just one of the Caribbean's most striking stretches of coast, quietly existing between the luxury villas that dot the hillside above.
The Experience
Walking Baie Longue from end to end takes a solid twenty minutes, and every step reveals a slightly different shade of blue. The sand is fine and pale, the kind that stays cool under morning feet and turns golden in the late afternoon. Swimming conditions vary by season — calm and inviting during summer months, more dramatic with winter swells that attract body surfers. The northern end tends to be quieter, sometimes completely empty on weekdays. Sea turtles nest along this stretch, and you might spot one surfacing just beyond the break. Catamaran tours often anchor here for a swim stop, giving you a glimpse of the beach from the water that explains why sailors have always loved this bay. The Terres Basses neighborhood adds an air of exclusivity without restricting access — the beach itself is public and free.
What to Try
Walk the full length at sunrise when the sand is unmarked and the light turns the water impossible shades of blue-green. Bring a snorkel to explore the rocky edges at the northern end where tropical fish gather. Pack a picnic — there are no vendors, so come prepared with everything you need for a perfect beach day. Watch for sea turtles surfacing in the calm morning waters.
Insider Tip
The small parking area fills up on weekends by mid-morning. Arrive before 9 AM or come late afternoon for the best sunset position on the island — the beach faces due west with unobstructed horizon views. During turtle nesting season (April-November), you might find marked nesting sites along the upper beach.
