Hamsterley Forest is a commercial forest in County Durham operated by the Forestry Commission. It is the largest forest in County Durham and covers more than 2000 hectares. Recreational activities are promoted within the forest and are focussed at the eastern end around the visitors centre. In addition to the visitors centre there is an adjacent cafe, an education room, toilet facilities and an independent bike shop called Wood'n'Wheels that also hires out bikes.
During the 1930s, the Forest was planted and tracks were built by unemployed men supplied through the Ministry of Labour. Most came from the mining communities and shipyards of the North East of England. They were housed in one of a number of Instructional Centres created by the Ministry, most of them on Forestry Commission property; by 1938, the Ministry had 35 Instructional Centres across Britain. These were basically work camps, where unemployed men carried out heavy labour and lived on site in wooden huts. The Instructional Centres were closed in 1938, as unemployment declined in the run-up to war, but some of the huts can still be seen around the Visitors' Centre, which was originally built as the camp's refectory. The Visitors' Centre was part of a prisoner of war camp during the Second World War.
A number of Mesolithic, Neolithic and Bronze Age flint tools have been found in Doctor's Gate Quarry. An area of the forest is probably the site of a 15th century iron ore processing site. An area next to Linburn Hall Wood was the site of a medieval convent.
Mountain Biking 
Mountain bike trails are developed in the forest by Hamsterley Trailblazers which were constituted on 5 January 2004. There are four official routes: Green (easy), Blue (moderate), Red (Difficult) and Black (expert) all of which are waymarked with colour-coded marker posts.
"The Loop" is a skills development circuit which includes features such as rock gardens and north shore obstacles. Features are graded from blue to black therefore helmets should be worn and it is not suitable for occasional/family cyclists.
Descend, a private club established in 2000 operates mountain bike 4X and downhill courses in the area south of the Grove.
