Cap Island Conservation Park is located 7.5 km offshore, west of Mount Misery, Eyre Peninsula. The park covers Cap Island's 8ha surface. The island consists of a granite base and a calcarenite mantle; its margins steeply over-hanging and eroded. Typical vegetation is a low Nitre Bush (Nitraria billardierei) shrubland. Cap Island Conservation Park was constituted by statute in 1972 to conserve a sea bird breeding area and Australian Sea-lion (Neophoca cinerea) and New Zealand Fur-seal (Arctocephalus forsteri) haul-out areas. Cap Island also bears the alternative name of Rocky Island.

The island was proclaimed a Fauna Conservation Reserve in 1967 and gazetted as the Cap Island Conservation Park in 1991. The conservation park is classified as an IUCN Category Ia protected area.
