Canunda National Park, Nature reserve in The District Council of Grant, Australia

Canunda National Park is a protected area stretching about 40 km along the South Australian coast from Cape Buffon to Cape Banks, roughly 350 km southeast of Adelaide. Its northern part has limestone cliffs, steep shorelines and reefs close to the coast, while the south is dominated by shifting dunes and beaches held by foredunes. The southern section borders Lake Bonney, one of Australia's largest freshwater lakes.

The area served as home to the Boandik People over many generations, who established camps along the coastline and utilized this region. This ongoing occupation reflects the deep historical connection between Aboriginal communities and this coastal landscape.

The Boandik people spent summers in temporary camps along this coast and moved inland to swamps for the rest of the year, living in more permanent huts called wurlies. Their seasonal round shaped how the land was used long before the park was declared.

The park office is in Southend at the northern end. Most of the park is accessible only to four-wheel-drive vehicles and walkers, so plan your route accordingly. The beaches can be dangerous for swimming.

The area is known for its mobile dunes that constantly shift through wind action, creating changing beach profiles. Anglers regularly visit to catch mullet and salmon in the coastal waters.
