Deep Creek Conservation Park is a protected area consisting of about 45 square kilometres (17 sq mi) of natural Australian bush land located on the southern coast of Fleurieu Peninsula in South Australia, 11 kilometres (6.8 mi) east of Cape Jervis. The total of 18 kilometres (11 mi) of coastline include views across Backstairs Passage to Kangaroo Island. The gullies contain orchids and ferns, while the hilltops have stunted scrub and low windswept trees. Walking trails (including part of the famous Heysen Trail) provide access to most of the park.
