  description: South Point is an accessible left-hand point break near Gracetown that offers forgiving walls for beginner to intermediate surfers. One of the few Margaret River breaks that still works in a southwest wind, making it a reliable option when the main breaks are blown out. The wave wraps around the rocky point and peels along the inside, offering long rides on clean days. Rarely crowded.
