The Box

Margaret River, Australia
⚠️Shallow🪸Sharp reef😮‍💨Hold-downs🦈Sharks🏝️Remote

The Box is one of the most feared waves on Earth—a mutant right-hand slab that produces square-shaped barrels of terrifying intensity over a barely submerged reef shelf. When solid SW swells wrap into the Margaret River region, The Box jacks up and throws over almost dry reef, creating a wave that's less surfed than survived. Wipeouts are catastrophic, injuries are common, and respect is mandatory. It's a testing ground for the world's best slab riders and a place most surfers are content to watch from the cliff.
