Cape Le Grande National Park consists of undulating sand plains, rich in coastal heath lay around massive granite and gneiss outcrops. Dispersed throughout are small freshwater pools and swamps.

The coastal scenery is most spectacular with rock outcrops, magnificent white sand, blue water and many islands.

The park is named after Le Grand, an officer of the L’Esperance, one of the ships in a French expedition commanded by Admiral D’Entrecasteaux in 1792. The Thistle Cove area is named after Matthew Flinders’ ship master, John Thistle. He drowned during exploration of the area in January 1802.
