Hankley Common is a 560 ha nature reserve and filming location in the south-west of Elstead in Surrey. The site is part of the Thursley, Hankley and Frensham Commons Special Area of Conservation, Special Protection Area and Site of Special Scientific Interest. The site has woodland and lowland heath with heather and gorse. Birds include nightjars and Dartford warblers and there are other fauna such as adders and common lizards. Access is subject to the needs of military training, with frequent training exercises and multiple buildings present.

Atlantic Wall reconstruction

D-Day training sites were created in Britain in order to practise for Operation Overlord, the invasion of Northern France by allied forces in 1944. In 1943, in an area of the Common known as the Lion's Mouth, Canadian troops constructed a replica of a section of the Atlantic Wall. It is constructed from reinforced concrete and was used as a major training aid to develop and practise techniques to breach the defences of the French coast prior to the D-Day landings. The wall is about 100 m long, 3 m high by 3.5 m wide. It is divided into two sections between which there were originally steel gates. Nearby are other obstacles such as dragon's teeth, reinforced concrete blocks and lengths of railway track set in concrete and with wire entanglements. Many of the relics show signs of live weapons training and the main wall has two breaches caused by demolition devices including the Double Onion: a specialised demolition vehicle, one of Hobart's Funnies, based on the Churchill tank. The reinforced concrete was made with rebars varying from 10 to 20 mm thick. Over the years the wall has become colonised by alkaline-loving lichens, mosses, ferns and other plants because the concrete provides the lime-based substrate that these species require and which is found nowhere else in the locality. They present an unusual range of plants to be found in an expanse of acid heathland. The preservation of the Wall is managed by Army Training Estates with the assistance of the MOD Hankley Conservation Group.

Golf course

Hankley Common is home to Hankley Common Golf Club which opened in 1897 with nine holes and was expanded to eighteen holes in 1922.

Film and television

Hankley Common has been used in Hollywood blockbuster movies and TV shows.

Bossom air crash

In July 1932 a Puss Moth aircraft carrying Mrs. Emily Bossom, Bruce Bossom, the American wife and eldest son of politician Alfred Bossom, and Count Otto Erbach-Fürstenau, broke up in mid-air. At least two of the occupants fell to the ground on Hankley Common. The sites where they fell are marked with memorial stones.

The Wigwam Murder

In September 1942, Hankley Common was the site of a murder. The victim was a woman who was living rough in a crude shelter made of tree branches in the manner of a wigwam, thus leading her to become known among locals as "the Wigwam Girl" and the murder case itself to be known as "the Wigwam Murder". She was eventually identified as 19-year-old Joan Pearl Wolfe.

2022 wildfires

In July 2022, during the 2022 United Kingdom heat wave, a series of wildfires took place in the common, each of which was described by the fire services as a "major incident". The smoke was strong enough to have been seen on the runway of Heathrow Airport as well as in Guildford. During the largest blaze of 24 July, Surrey Fire and Rescue urged nearby residents to keep windows closed and pets inside until the blaze was extinguished by the 19 vehicles in attendance. Several nearby residents were evacuated until the fire was brought under control. To protect the structures on the common and the valued training area, the MoD provided a contracted Eurocopter AS350 for aerial firefighting operations. Water for this was collected from nearby Frensham Great Pond, and this marked the first use of aerial firefighting equipment in Surrey. The fires combined destroyed almost 70 hectares of the site and caused extreme damage to protected habitats.
