Eucla National Park, Nature reserve in Western Australia, Australia

Eucla National Park covers 35.6 km² of mallee scrub and heath on the southern coast of Western Australia, 1,238 km east of Perth. Its southern edge meets the Great Australian Bight, and Wilson Bluff and the Delisser sandhills rise within the park. Templetonia retusa, with red, pink or yellow flowers, grows throughout, and a rare Senecio species lives on the limestone cliffs.

At the western end of the park lie the ruins of the original Eucla township and its telegraph station, both partly buried by encroaching sand dunes. The park, 1,238 km east of Perth and covering 35.6 km², borders the Great Australian Bight to the south.

The park's western end holds the ruins of the original Eucla township and the Eucla Telegraph Station, both partly buried by drifting sand dunes. Visitors can walk among these remains, which mark the old telegraph line route across the Nullarbor.

A four-wheel drive vehicle is necessary to visit, as the park has no sealed roads throughout its interior. Bring plenty of water and supplies, and check conditions beforehand since access can vary with weather.

The park covers 35.6 km², and its western end holds the ruins of the original Eucla township as well as the old telegraph station, both partly buried by drifting sand. The dunes are still moving, so the structures disappear and reappear over time.
