Dingley Dell Conservation Park (formerly known as the Dingley Dell National Pleasure Resort) is a protected area in the Australian state of South Australia located in the state's south east in the gazetted locality of Port MacDonnell about 4 kilometres (2.5 mi) north-west of the town centre of Port MacDonnell and about 26 kilometres (16 mi) south of the city centre in Mount Gambier.

[2][4] The conservation park occupies land in Part Section 138 of the cadastral unit of the Hundred of MacDonnell.

It was purchased by the Government of South Australia in 1922 at “the request of the Dingley Dell Restoration Committee.” The land originally gained protected status as a national pleasure resort proclaimed under the National Pleasure Resorts Act 1914 and which was managed by the South Australian Tourist Bureau.

[6] Gordon's former home which was listed on the South Australian Heritage Register on 24 July 1980 under the name of the Dingley Dell Museum is managed by a commercial operator.

[7][8][9] As of 1994, visitation was “low” with “the majority of visitors viewing the cottage, and a lesser proportion using the walking track behind the cottage.”[2] As of 2014, the conservation park had not been given an IUCN protected area category.
