The Guillotine

Gracetown, Australia
🪨Rocks🦈Sharks🏝️Remote

The Guillotine is an exposed left-hand reef break near Gracetown that delivers very consistent waves. The reef picks up virtually any swell going and works best around mid tide when the wave produces clean, defined walls with barrel sections. The isolated location keeps crowds to a minimum, but the rocky reef and shark-prone waters demand respect. A solid intermediate option in the Margaret River region.
