Crowdy Beach is a long, expansive stretch of coastline within the Mid-Coast Council region of New South Wales, Australia. At 14.8 kilometers in length, it is the longest beach on this section of coast, forming a sweeping curve from Kylie Beach in the north to Crowdy Head in the south. The beach is predominantly located within the protected Crowdy Bay National Park, preserving a landscape of coastal heathland, swamps, and a significant bird habitat on Pleistocene barrier deposits. The southern end of the beach faces northwest in the lee of the prominent 55-meter-high Crowdy Head, which shelters a small fishing port settlement. The beach features a classic double-bar surf system with rips cutting through an attached inner bar, a deep trough, and an outer bar. Sand becomes very fine and the beach wide and firm towards the south, where wave height diminishes and the surf zone becomes a wide, low gradient area, though a permanent rip exists against the boulder beach leading to the head. This combination of exposed surf, sheltered bay, and proximity to the Harrington-Crowdy Head estuary makes it a versatile destination for shore-based anglers.
