Национальный парк Дхилба Гууранда–Иннес: Природа и история полуострова Йорк.

Protected area in the Yorke Peninsula, South Australia

Dhilba Guuranda–Innes National Park, formerly Innes National Park, is an IUCN designated protected area in the Australian state of South Australia located on the southwest tip of Yorke Peninsula about west of the state capital of Adelaide. It is a popular destination for camping, bushwalking, fishing, surfing and scuba diving.

The Narungga people occupied the Yorke Peninsula for thousands of years. They consisted of four clans, the Kurnara of the north, the Windera of the east, the Wari of the West and the Dilpa of the south. They are the traditional owners of the land, and have strong cultural links to it, with some sites having particular spiritual significance. European colonisation of the area began in 1846 with sheep grazing near Cape Spencer. Crops were grown on a small scale in the 19th and early 20th century. Innes National Park was named after William Innes, who discovered commercial quantities of gypsum in the early 1900s and founded the mining town of Inneston in 1913, which had a population of around 500 at its peak. Gypsum was mined until 1930 when the Great Depression made it uneconomical, and in 1970 the town and surrounding land was sold to the South Australian government, creating Innes National Park. Some gypsum mining still continues at nearby Marion Bay.

The national park was declared on 5 March 1970 under the National Parks Act 1966 as the Innes National Park, to "conserve important habitat for the western whipbird, the mallee fowl and to protect a number of heritage buildings at Inneston". Land was added to the national park in 1977, 1984 and 1993 in order to deal with increased recreational use. Some of the buildings at Inneston have been restored and are available as basic hire accommodation.

Dhilba Guuranda–Innes National Park is located on the southern western extremity of Yorke Peninsula in South Australia about by road from the Adelaide city centre. It is located within the locality officially known as Inneston.

The national park occupies most of the land on the south western tip of Yorke Peninsula south west of a line running from Willyama Bay on the south coast of the peninsula near Marion Bay to Gym Beach on the west coast of the peninsula and the following four islands immediately adjoining the coastline (from east to west): Chinamans Hat Island, Middle Island and South Island west of Pondalowie Bay, and Royston Island immediately west of Royston Head. Within the above area, land excluded from the national park includes the following saline lakes which were associated with gypsum mining at the time of proclamation of the national park Marion Lake, Snow Lake and Spider Lake.

The national park is serviced by a road connected to the western end of the Yorke Highway which passes through Marion Bay. The road which starts at Stenhouse Bay follows the coastline as a sealed road passing Chinamans Hat Island, Cable Bay and the turn offs to Cape Spencer, Ethel Beach, West Cape and two camping grounds at Pondalowie Bay. The road concludes as a sealed road at the turn off to the Pondalowie Surf Break Carpark. It continues as an unsealed road, passing turn offs to Dolphin Beach and Shell Beach, to terminate at Browns Beach in the north west of the national park. Gym Beach in the extreme north west, while being accessible via the national park's walking trail system can only reached via vehicle from the Marion Bay Road which is located to the east of the national park's boundary. The national park is within the extent of an Important Bird Area known as the Southern Yorke Peninsula Important Bird Area, identified as such by BirdLife International because it supports populations of mallee fowl as well as of other threatened bird species such as the western whipbird.

As of 2003, 333 species of native plants had been recorded in Dhilba Guuranda–Innes National Park of which 115 species were of conservation significance including 24 scheduled in the South Australian National Parks and Wildlife Act 1972 and the following four species listed in the Australian Environment Protection and Biodiversity Conservation Act 1999: annual candles, winter spider orchid, bead samphire and splendid bush pea.

The national park was listed on the former Register of the National Estate because of its natural and European heritage.

The following three lakes which support a population of stromatolites are listed on the South Australian Heritage Register maintained by the South Australian Government: Deep Lake, Inneston Lake and Marion Lake.

As of 2003, 21 sites of significance to the Narungga people had been identified. These consisted of "burial sites" and a broad classification known as "archaeological sites".

The following two sites at Inneston and Stenhouse Bay associated with the mining of gypsum are listed on the South Australian Heritage Register the "Inneston Gypsum Complex" and the Stenhouse Bay Jetty.

At least four shipwrecks which are located within the national park or immediately adjoining its coastal boundary are protected under Australian and state historic shipwrecks legislation, that is the Underwater Cultural Heritage Act 2018 (Cwth) and the Historic Shipwrecks Act 1981 (SA). SS Marion which run aground to the immediate east of Chinamans Hat Island during 1862. The barque Ethel, which run aground on the coastline between West Cape and Cape Spencer on a beach now known as Ethel Beach during 1904. The remains of the Ethel lie parallel to the shore below the cliff at Ethel Beach. For many years the hull was largely intact, deteriorating gradually with every storm. A severe gale in 1988 caused the hull to completely collapse, leaving the iron frame as the most identifiable feature of the site. The wreck is mostly covered by sand, sometimes revealed more during storms. SS Ferret which run aground in 1920 on what is now Ethel Beach. Hougomont which was scuttled in 1932 to form a breakwater lies close to the coastline near Stenhouse Bay.

Camping grounds are available at the following locations (from east to west) Stenhouse Bay, Cable Bay, Pondalowie Bay (three sites including one for caravans and trailers), Shell Beach, Browns Beach and Gym Beach.

Indoor accommodation is available at three locations a number of restored buildings at Inneston, the Stenhouse Bay hall and a cottage at Shell Beach.

A system of trails allows visitors to the national park to enjoy views of the coastline and adjoining waters and to observe flora and fauna including species such as southern right whales and dolphins and features such as lighthouses and heritage sites. As of 2014, there are three major walking trails the Thomson Pfitzner Plaster Trail Hike that connects Stenhouse Bay and Inneston, the Royston Head Hike from Dolphin Beach to Royston Head and the Gym Beach Hike which connects Browns Beach and Gym Beach. A number of minor trails connect the road system to locations such as Cape Spencer, Ethel Beach, West Cape and Pondalowie Bay.

The main surf break at Pondalowie is a popular quality wave. It consists of a combination left and right peak that breaks over a reef and sand bottom. The left is good up to about 4 feet (1 m). The right starts to become good from between 3 feet (1 m) and 8 feet (2 m) plus. A second smaller right hand reef break known as "Richard's Reef" is located further north along the beach. It was named in honour of Richard Thomas, a long time local surfer and resident of the area. Not far from Stenhouse Bay is a break known as "Chinaman's". This is a powerful and hollow left hand reef break which breaks in shallow water and washes over a rock shelf. It is a high quality wave that is suitable only for skilled surfers, and caution should be used when surfing here.
