From 1981 onwards, plans were published that aimed to develop the area for commercial purposes, but public pressure led to its declaration as a public reserve in 1989. The last land added was a small area in 2003. Anstey Hill is a 371 metres (1,217.2 ft) high peak in the park's south.

Today's park

Anstey Hill Recreation Park is a reserved area of public land with short seasonal creeks, low hills and steep-sided gullies.

, weed control, ruin stabilisation and creation of walking trails. There are no visitor facilities or amenities except for walking trails, most of which follow fire access tracks; a single constructed pedestrian trail leads to Klopper’s Quarry. The park is mostly designated as a "conservation zone" where only passive recreation, including walking dogs on leads, is permitted. Horses and motor vehicles are not allowed and only the main tracks are maintained.

In recognition of the established and popular activity of mountain biking in the greater Adelaide area, and to better accommodate the mountain biking community in the North Eastern suburbs, the Department for Environment and Heritage has proposed to permit cycling in designated zones on purpose-built tracks and on certain management tracks within the park. The intention is to satisfy both biodiversity and recreation objectives in the park and reducing the incidence of illegal mountain bike riding in other non designated areas.

Anstey Hill Park lies between Bureau of Meteorology measured rainfall contour lines that denote an annual average from 580 to 820 mm (22.8 to 32.3 in). It has hot dry summers, as does all of Adelaide, and December to February's average maximum daily temperatures 28 °C (82 °F) to 29 °C (84 °F). Temperatures drop significantly in the wetter winters; July's average maximum temperature is 14.6 °C (58.3 °F). Apart from springs in Water Gully, the site of Newman's Nursery ruins, all of the numerous creeks in the park are seasonal and dry for much of the year. The park rises from approximately 220 m (721.8 ft) above mean sea level on its western side to 420 m (1,378 ft) at the highest point in the park's southeast corner. Most of the park is steeply sloping with gradients steeper than one in four. Except for the base of Water Gully, topsoil throughout the park is shallow and low in plant nutrients.

There are frequent serious bushfires in the park. Much of the reserve was burned in 1980, eastern parts burned in 1981, and most of the park burned again in the 1983 Ash Wednesday fires
Ash Wednesday fires
The Ash Wednesday bushfires, known in South Australia as Ash Wednesday II, were a series of bushfires that occurred in south-eastern Australia on 16 February 1983. Within twelve hours, more than 180 fires fanned by winds of up to 110 km per hour caused widespread destruction across the states...

; Newman's Nursery's remains were devastated during the 1983 bushfire. As recently as 2004, a major fire burned over 100 ha (247 acre) of bushland next to Anstey Hill. Most fires in the park are deliberately lit and the park is regarded as a "hotspot" for arson

 inquiry. The park has more than one arson attack, on average, each year. In the hill's face, encompassing Anstey Hill, approximately 60% of all fires (1999–2004) are deliberately lit and less than 5% are classed as naturally occurring. Most deliberately lit fires begin at the park's boundaries and are contained within it.

Naming

The name of the park derives from a road built by George Alexander Anstey
George Alexander Anstey
George Alexander Anstey was born at Kentish Town, London. He was the eldest son on Thomas Anstey, an early settler in Van Diemen's Land . George migrated to Tasmania at the age of thirteen and arrived in Hobart in February 1827 with Thomas 'Chiz' Chisholm Anstey, one of his younger brothers, in...

, a South Australian pastoral and horticultural pioneer. Anstey established Highercombe Estate on two land sections east of the park that he purchased in 1840. He built a private road to his estate, which ran along the base of a gully and up a steep hillside. The road was initially named "Anstey Hill Road"; this name was later used for the hill, the subsequent land reserve and the current recreation park.

The Gun Emplacement was officially named as such in 1997 after a period of unofficial usage. This name was first used by Major William Hubert Edmunds, a Lieutenant cartographer

 who later enlisted in the Commonwealth of Australia forces. After leaving the military, Edmunds carried out "reconnaissance surveys" on the fringes of the Adelaide metropolitan area. As part of the work, he took particular note of an unusual plateau at the edge of what is now Tea Tree Gully. By the time his work was published in 1926, he had named the plateau "The Gun Emplacement", presumably for its suitability as a location for a field gun

Foundation

In 1962, the South Australian Planning Authority's town planning committee released a report on the development of metropolitan Adelaide. The report, in part, recommended that a regional park be established north of Anstey Hill and southeast of Tea Tree Gully. The stated intention was preservation of the character of the face of the foothills, as visible from Adelaide’s suburbs. From 1966 to 1977, land was purchased under the auspices of the State Planning Authority, for what was then "reserve 13".

One notable purchase was of 73 hectares (180.4 acre) in 1969, of which 16 hectares (39.5 acre) was an active quarry operated by Quarry Industries. This quarry was known as the Tea Tree Gully freestone quarry and today lies in the park's northwest. It had a permit to operate until December 1970, which was later extended to December 1980. Additional land affected by the quarrying was purchased in 1971. By the end of the lease, rehabilitation work completed did not meet the standard required by the Planning Authority. Quarry Industries vacated the site in April 1982, other firms then contracted to continue rehabilitation work. Land beneath the Gun Emplacement was subdivided

 for housing in 1966. A developer unsuccessfully attempted to have the plateau subdivided in 1975. The site was purchased by the government in 1978 and added to the then Anstey Hill Reserve. During the 1970s, part of the park's area was earmarked to be subdivided and developed for housing. Significant opposition to this use, due to the land's historical and scientific significance, came from the South Australian division of the Geological Society of Australia

 and the state's Field Naturalists Society.

The Planning Authority established the Anstey Hill Joint Steering Committee in 1981, initially to prepare a concept plan for development of the reserve. The draft report was published in late 1981 with a proposal to spend up to $3.5 million establishing the park. Uses were explored including: a rock climbing area, motocross circuit, kiosk, cycle track, horse riding area, caravan and camping grounds and a restaurant. In 1983, the state Department of Environment and Planning published the final concept plan for the "Anstey Hill Regional Park". The plan indicated that a caravan park, or possibly a velodrome

, might be an appropriate development. There was significant interest by developers to use parts of the park commercially. Increasing public opposition to this concept led to the declaration of the entire reserve as a public recreation park. The Friends of Anstey Hill Recreation Park volunteer group was formed in 1990. Most of the then 306.5 ha (757.4 acre) park was proclaimed on 31 August 1989 with a smaller 55.5 hectares (137.1 acre) addition in October 2001. It was officially opened by Environment and Planning Minister Susan Lenehan

 in a ceremony on 17 September 1989. The Department for Environment and Heritage added one last section to the park in 2003. A wedge of land 15 by remained from a purchase by George Dickerson in 1857. This land formed part of a cliff and had long been managed as part of the park. No known current owner was found and the Department compulsorily acquired the land and added it to the Recreation Park.

Land use

Although it lies within the traditional lands of the Aboriginal Kaurna people, no occupation sites have been found. Much of the park has been used for agriculture since European settlement. Significant European uses of the park's land have been Newman's Nursery, a main road, mines, quarries and a water filtration plant.

Newman's Nursery

The remains of Newman's Nursery, established by Charles Newman and his family in the second half of the 19th century, are situated within the park at the base of Water Gully. After living on a rural property near Houghton

The Newmans developed a nursery on the site between 1857 and 1871, over time assisted by their 17 children. There were hothouses in operation by 1870, and produce from the site was shown in exhibits from 1871. At maximum extent in the late 19th century it had its own dairy

s. The nursery was a frequent prize winner at agricultural fairs and exhibitions. At the Great Exhibition for the Queen’s Jubilee in 1887, the Newmans won two "First Orders of Merit", the exhibition's highest award, and all three "Exhibition Diplomas" on offer. Charles Newman died in 1889 after falling from his horse, and control of the nursery passed to his sixth son, Frederick.

During a severe storm in February 1913, 2 inches (5.1 cm) of rain fell in an hour, setting the streams, creeks and roads awash and damaging the nursery. In October of the same year, another storm destroyed buildings and plantings. Due to the extent of the destruction, and the lack of funds for full repairs, the nursery never fully recovered. Frederick Newman left the nursery in 1925 to run a smaller one in Tea Tree Gully, next to North East Road; control of the original nursery passed to Harry Newman. With the death of Charles' wife Mary Ann in 1932, the property was sold and subsequently used as a dairy. It changed ownership again in 1935, then used for sheep grazing. The new owner removed everything of value from the property; slate

 shop and a new road. With no economic finds, the company closed in July 1889. The quarry, in Water Gully adjacent to the nursery's ruins, has been mined for blue dolomite, some of which was used for the nursery's buildings. Quarries elsewhere in Water Gully were opened in the 1880s and intermittently supplied quartzite road metal for the District Council of Tea Tree Gully. A crushing plant was erected on the north side of the gully in 1912 to create this road material.

When the park was proclaimed, land zoning regulations allowed existing mining prospecting rights to continue. These rights were restricted to previously mined areas; this coupled with further restrictions imposed by the National Parks and Wildlife Service Act (1972) make it unlikely that mining will occur in the future.

. Rumps Bakery was built in 1854 with local stone. From 1867 to 1893 it was rented to Charles Rumps, who started Tea Tree Gully's first bakery in the building in 1872. In 1894, the building was sold to Ernest Heitmann, who continued to use it as a bakery. Until the mid-20th century, the Ellis family and an adjacent general store frequently used it for storage. Assisted by a government grant and supervised by the Department of Environment and Heritage, the Friends of Anstey Hill stabilised both buildings in 2000.

Water filtration plant

In the 1970s, the Engineering and Water Supply Department chose an area at the top of the park, adjacent to Lower North East Road, to build a water treatment works. Based partly on seismic refraction traverses, a ridge underlain by dolomite and quartzite was deemed to be stable enough for construction. The site was also selected because of its hydraulic advantages; all other sites would have required the construction of a major pumping station. The exact placement of the site was made so that it could not be seen from the metropolitan area. It has a design flow of 313 megalitres (ML) per day with a maximum capacity of 344 ML. The plant was commissioned in 1980 and uses filtration and sedimentation techniques to clean water from the Mannum to Adelaide pipeline. It was the second plant in Adelaide, after the opening of the Hope Valley plant in 1977. Most of the water is piped directly from the River Murray, but some is sourced from Millbrook Reservoir

Roads

Lower North East Road runs around Anstey Hill and up the escarpment of the Burnside-Eden Fault Zone. It connects the suburbs—formerly villages—of Hope Valley and Houghton. Three roads were surveyed and built to connect the same locations. The first was a private road constructed by George Anstey in 1841—although officially surveyed in 1844—to reach his estate, as a mostly straight-line extension of Grand Junction Road. It followed the base of a gully, before rising steeply up Anstey Hill. From 1842 to 1846, Anstey constructed a replacement private road with a devil's elbow (double hairpin bend) that followed the land's contours more closely. As Chairman of Roads for the District of Yatala, Anstey allocated most of the district's funding to his road, leading to a public outcry that forced him from office in 1851. This ungravelled road became known as Anstey Hill Road and remained in use for 20 years. New Road, later renamed Houghton Road and subsequently Lower North East Road, was constructed in 1873 as a replacement. It was longer than the preceding roads but lacked a devil's elbow, was more evenly sloped, and was paved

Perseverance Road, and some housing, defines the western edge of much of the park. William Haines was the district clerk for Tea Tree Gully from 1867 to 1902 and Member of Parliament for Gumeracha from 1878 to 1884. Since 1862, he had lobbied for construction of a road to link Tea Tree Gully to Anstey Hill Road. The 1–½ mile road was eventually approved and subsequently opened in 1880. Known as Haines' Folly before its completion, it was officially called Haines' Perseverance Road at the opening ceremony.
