Thetford Forest is the largest lowland pine forest in Britain, Thetford Forest Park is located in a region straddling the north of Suffolk and the south of Norfolk in England. Breckland Forest is found within Thetford Forest Park and constitutes 28,947.4 Ha in the form of a Site of Special Scientific Interest.
Thetford Forest was created after the First World War to provide a strategic reserve of timber, since the country had lost so many oaks and other slow-growing trees as a consequence of the war's demands. It is managed by the Forestry Commission. The creation of the forest destroyed much of the typical Breckland environment of gorse and sandy ridges, ending the frequent sand blows (where the wind picked up sand and blew it across the land reducing visibility). However, this environment was itself man-made, since the area had been denuded by flint-mining, the construction of rabbit warrens and other activities. Grimes Graves is located within the forest.
The forest is largely surrounded by farmland, as well as the villages of West Stow, Ingham, Elveden, and the towns of Mundford and Thetford in Norfolk, and Brandon in Suffolk, however it has a high level of biodiversity. It is home to a large population of hares, rabbits and gamebirds. Several species of deer also reside there, Muntjac, Roe Deer and a small population of Red Deer, the last hunted by the Norwich Staghounds before deer hunting was outlawed. 
The forest is well known for its scarce breeding birds, such as Woodlark, Nightjar, Goshawk, Crossbill, Siskin as well as an introduced population of Golden Pheasant. All of these can be found at the Mayday recreation site. Stone Curlew breed on the edges of the forest and there is often a wintering Great Grey Shrike.
High Lodge Visitors Centre
High Lodge Visitors Centre has a restaurant, gift shop, cycle hire, adventure play area, walking trails, paintballing arenas, outdoor concerts, theatre and entertainment. It is also the home to the Go Ape high wire adventure course. 
The forest is a popular destination for mountain biking, and has several marked trails ranging from those suitable for families, to the Black Trail for experienced riders. The forest also has hundreds of miles of singletrack, several bomb holes and a steeply undulating section called The Beast.
National cross-country cycling races are held in the forest. There is also a recently formed organisation called TIMBER (Thetford Improved Mountain Biking EnviRonment) which aims to work with the Forestry Commission to improve the mountain bike trails in the forest.

The Roman road, known as Peddars Way leads from the north Norfolk coast and reaches its end in Thetford Forest, near Knettishall. Other walking routes in the Forest connect to it. There is also a walk way through the trees called 'Go Ape'. There is a Center Parcs holiday resort at Elveden which also brings many visitors. The British Siberian Husky Racing Association  hold several husky racing events in the forest each winter.
A sizeable proportion of Thetford Forest and the surrounding woodlands is reserved for military activities in an area known as Stanford Battle Area, with public access forbidden.
