  description: Broken Head is Byron Bay's step-up wave—a right-hand point/reef break south of town that delivers hollower, more challenging conditions than the mellow Pass. The wave breaks over rock and reef with barrel sections that reward committed surfers. The setting is stunning, with the headland surrounded by nature reserve and eucalyptus forest. While it's only a short drive from Byron, the vibe is more serious and the locals less tolerant of drop-ins. When The Pass is too crowded or too small, Broken Head offers a genuine step up in both quality and consequences.
