La Cúpula

Antofagasta, Chile
🪸Sharp reef🪨Rocks⚠️Shallow

La Cupula is Antofagasta's signature bodyboarding slab, a left breaking over shallow rock in Chile's dry northern coast. It has hosted international bodyboarding events because the wave can deliver thick, technical barrels when south-southwest swell and clean wind line up. The setup is close to the city but still serious, with reef, rocks, and heavy sections making it best for confident riders.
