Cape Arid National Park is a national park located in Western Australia, 731 kilometres (454 mi) southeast of Perth. The park is situated 120 kilometres (75 mi) east of Esperance and lies on the shore of the south coast from the eastern end of the Recherche Archipelago.

The Archipelago of the Recherche, known locally as the Bay of Isles, is a group of 105 islands, and over 1200 "obstacles to shipping", off the south coast of Western Australia. The islands stretch 230 km (140 mi) from east to west and to 50 km (31 mi) off-shore encompassing an area of approximately 4,000 square kilometres (1,544 sq mi). The western group is near Esperance and the eastern group at Israelite Bay. They are located in coastal waters, part of which is designated the Recherche Archipelago Nature Reserve.
