Located 267 km south of Perth, Leeuwin-Naturaliste National Park is named after two locations with lighthouses at each end of the park, Cape Leeuwin and Cape Naturaliste.
The park covers over 100 miles and comprises 28 separate reserves, totaling about 15,600 ha. It is known for its limestone and granite outcrops, surf breaks and beaches, coastal cliffs, lakes and springs, rivers, and network of caves.
The Leeuwin-Naturaliste Ridge runs parallel to the coast from Cape Naturaliste to Cape Leeuwin. The Leeuwin-Naturaliste Coast is a strip of coastal dune limestone known as the Tamala Limestone Formation, while the Margaret Plateau is undulating and dissected and composed of basement rock. The ridge's geology and vegetation variations follow its north-south orientation.
The park is home to a diverse range of plant communities, including coastal herblands, grasslands, sedgelands, heaths, shrublands, woodlands, and forests. It also supports various bird species and indigenous mammals.
The creation of the national park was a result of conflicts between primary industries and land-use activities. The park is located on delicate land and requires conservation efforts.
In December 2021, a bushfire was intentionally lit in the park, resulting in the destruction of nearly 5,500 hectares.
The Cape to Cape Track, a 135-kilometer walking trail, follows the Leeuwin-Naturaliste ridge and was opened in 2001.
