Belharra Perdun is a well-known surf spot located about 2.5 kilometers offshore. It's famous among the European tow-in surfing crew, mainly due to its 15-meter deep, seagrass-covered shoal. This spot really comes alive during the winter months when the swells get big, creating an A-frame peak that can produce some impressive waves.

The optimal swell direction for Belharra Perdun is Northwest, but it can also handle swells coming from the West and North. When the swell hits around 15 feet (approximately 4.6 meters), the waves tend to break over a rock ledge, offering both left and right rides. Riders looking to catch the best waves should target low to mid tides, and the ideal wind direction is Southeast. It’s important to note that this spot is meant for expert surfers only, as the conditions can get pretty intense.

One key point for spectators is that the action can be viewed from the cliffs along the coast road between Socoa and Hendaye, making it a popular spot for those wanting to watch some serious surfing from a safe distance.
