The Adelaide Hills are part of the Mount Lofty Ranges, east of the city of Adelaide in the state of South Australia. It is unofficially centred on the largest town in the area, Mount Barker, which has a population of around 29,000 and is also one of Australia's fastest growing towns.
The Adelaide Hills region is one of the cooler wine regions of mainland Australia as, despite warm days in January and February when the grapes are ripening, the region generally experiences cool nights. This significant diurnal variation results in cool mean daily temperatures even in summer and the consequence of this is high quality, cool-climate wines, leading to its world-famous reputation as a wine producing region. The numerous wineries and cellar doors are represented by a regional association called the Adelaide Hills Wine Region.
The Adelaide Hills were amongst the first areas of South Australia to be settled by European settlers. A number of towns in the Hills were started as German settlements; Hahndorf, and Lobethal are two widely known examples. The original town names and architecture still reflect this. Descendants of these first settlers and others of German origin still reside in the area. This explains the strong German cultural connection seen in the number of Lutheran churches, Lutheran schools which often have German on the curriculum, and the number of older residents who still speak German. Some customs have grown, such as the Lobethal Christmas lights which began in the 1950s.
For most Adelaide residents, a drive through the hills is a popular pastime, particularly due to proximity. With Adelaide being a linear city extending 90 kilometres (56 mi) north to south, the hills are within 20 kilometres (12 mi) of the majority of residents. Other significant attractions are the slightly (2–3 degrees) cooler temperatures in summer, lush green and sometimes frosty winters and the picturesque old-world towns situated largely among scenic landscapes. The Mount Lofty area, home to Adelaide's television transmission towers, has a lookout area, restaurant and a fire-spotting tower run by the Country Fire Service. The area receives a light snowfall approximately once every three to four years, occasionally enough to stay on the ground for half a day.
The Adelaide hills region is close enough to commute to the city, yet is the gateway to the country, so residents enjoy the best of both worlds – the country community life and the convenience of the city. Desirability of the area has increased, particularly since realignment of the road and construction of the Heysen Tunnels on the South Eastern Freeway improved road access. Rising real estate prices reflect this. The tunnels, completed in 1999 are named after Sir Hans Heysen, an eminent local landscape painter whose home and studio, "The Cedars", has been maintained as a cultural site located near Hahndorf. To this day, Hahndorf itself supports a thriving community of artists and craftspeople, either in the town or nearby countryside.
The hills region is also a premier wine region within Australia and also one of the oldest. The veritable maze of valleys and sub-valleys, with slopes offering every conceivable aspect, means there is as much mesoclimatic variation as one can find anywhere in Australia, making generalisations of wine type very hazardous. The first vines were planted in the Hills in 1839, three years after South Australia was declared a province, a case of that wine was delivered to Queen Victoria in 1844. There are over 50 wineries (2005) within the Hills region which are open most days for tasting and cellar sales.
The area is home to the annual Medieval Fair held at Gumeracha across one weekend every April, and the English Ale Festival, also annually held each May. Highlights of the Medieval Fair include live jousting tournaments held on horseback, blacksmithing and dance demonstrations, needlework and costume creation, and authentic music provided by wandering troubadours. The genesis and popularity of these two colourful festivals, where patrons are encouraged to come in costume, springs from the relatively large numbers of British ex-patriates who reside in the Hills. Throughout the year there are folk music sessions and concerts held in various small towns like Mt Pleasant, Mylor and Balhannah - connected with this same cultural community. Gumeracha is also home to the largest rocking horse in the world, standing at 18.3 metres (60.0 ft) (approximately the height of a six-storey building) and open to the public, it serves to advertise an adjacent wooden toy factory and wildlife park. The town of Birdwood is home to the National Motor Museum and is the endpoint of the annual Bay to Birdwood run, in which more than 1,500 vintage motor vehicles are driven by their owners from Glenelg past the city and through the hills to finish at the museum where a festival is held. The museum holds a large and historically important collection of cars, motorcycles and commercial vehicles.
Protected areas 
The Hills region also has many conservation parks, including the Cleland Conservation Park with its free roaming kangaroos, wallabies and emus. The park also has enclosed areas for dingos, koalas, native birds & snakes, and is a popular destination for school groups as well as international visitors. Many native species of fauna can be encountered within the hills region. Among the more common species include the Kookaburra, Tawny Frogmouth, Southern brown bandicoot, Kangaroo, Brown Tree Frog, and Bearded Dragon. Several of the less common species include the Antechinus (Morialta Conservation Park), Heath Monitor (Scott Creek Conservation Park) and the very rare Inland Carpet Python (greater Mount Barker region). Many walking trails, including a portion of the Heysen Trail and bike trails, including the start of the Mawson Trail abound within the Hills. The Heysen Trail itself extends from the tip of the Fleurieau Peninsula, through the Adelaide Hills and on up to the Flinders Ranges, three hours drive north of Adelaide. Birds found in the Hills include some of the best-known Australian parrots such as the Adelaide Rosella, Rainbow and Musk Lorikeets as well as large cockatoos like the Major Mitchell, and the Yellow-tailed Black Cockatoo. Smaller but no less spectacular are the Superb Blue Wren and Eastern Spinebill.
