Deep Creek National Park, formerly the Deep Creek Conservation Park, is a protected area in the Australian state of South Australia located on the southern coast of Fleurieu Peninsula in the gazetted localities of Deep Creek and Delamere about 11 kilometres (6.8 miles) east of Cape Jervis.

[8] The park encompasses 18 kilometres (11 miles) of coastline, which include views across Backstairs Passage to Kangaroo Island.

The conservation park consists of mainly rolling coastal hills, the gullies of which contain orchids and ferns, while the hilltops have stunted scrub and low windswept trees.

[citation needed] It is classified as an IUCN class II protected area.

[1] In 1980, it was listed on the now-defunct Register of the National Estate.
