At Innes National Park sheer cliffs plunge into indigo waters and rocky offshore islands hide small coves and sandy beaches. Marion Bay (www.marionbay.com.au), just outside the park, and Stenhouse Bay and Pondalowie Bay, both within the park, are the main local settlements. Pondalowie Bay has a bobbing lobster-fishing fleet and a gnarly surf beach. The rusty ribs of the 711-tonne steel barque Ethel, which foundered in 1904, arc forlornly from the sands just south of here.
Follow the sign past the Cape Spencer turn-off to the ghost-town ruins of Inneston, a gypsum-mining community abandoned in 1930.
