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 230km from east to west and to 50km off-shore encompassing an area of approximately 4000km2. The western group is near Esperance and the eastern group at Israelite Bay. They are located in coastal and inland waters, part of which is designated the Recherche Archipelago Nature Reserve.
