Casernes is a beach located at the northern edge of Seignosse beaches. It offers typical beach access, requiring a 500m walk from the deep sand parking lot under the pines. While it can be a bit quieter than nearby spots like Penon, it often gets crowded, especially when the conditions are right. You’ll find a laid-back vibe here, and the location is a mix of regular beachgoers and a few nudists enjoying the sun.

The surf at Casernes can be pretty decent, especially when the sand aligns well. Optimal swell direction is from the Northwest, but it can handle swells coming from the West and North. The beach breaks are suitable for beginners, and they tend to work best at low, mid, and high tides. You can expect waves that break both left and right, with heights that are good for anyone looking for a fun session, starting from about 0.3 meters (1 ft). On those perfect mornings or evenings with an East wind, the waves can be fast and exciting.

While there are usually lifeguards around and options for surf schools and board rentals, it's good to manage your expectations. This spot is often just as packed as the more popular beaches nearby. Still, it can offer a good day of surfing, especially when the conditions line up nicely.
