About William Bay National Park

 

Located along the southern coast of Western Australia near the town of Denmark, William Bay National Park encompasses stunning coastal landscapes, including white sandy beaches, granite outcrops, and vibrant marine environments. The park protects a section of the Southern Ocean coastline characterized by rugged headlands and sheltered bays. Ecologically, it supports diverse native flora such as coastal heath and eucalyptus woodlands, and is a habitat for various birds and marine species. The park’s crystal-clear waters and sheltered bays create ideal conditions for snorkeling and swimming, particularly at popular spots like Greens Pool and Elephant Rocks, where smooth granite boulders and calm waters attract visitors year-round. The park also contains walking trails that wind through coastal heath and offer vantage points over the ocean and beaches. Established in 1966, William Bay is recognized for its natural beauty and recreational opportunities. Visitors enjoy activities ranging from beachcombing and picnicking to wildlife observation and photography. The nearby town of Denmark provides amenities and serves as a gateway, while the park’s relatively small size makes it accessible for day trips and short stays. The combination of geological features, clear waters, and diverse ecosystems positions William Bay National Park as a key protected area along Western Australia’s south coast. Visitor appeal also includes the chance to experience unspoiled beaches with limited development, making it a favored spot for relaxation and exploration in a pristine natural setting.
