Bleaklow is a high, largely peat-covered, gritstone moorland in the Derbyshire High Peak near the town of Glossop. It is north of Kinder Scout, across the Snake Pass (A57), and south of the A628 Woodhead Pass. Much of it is nearly 2,000 feet (610 m) above sea level and the shallow bowl of Swains Greave on its eastern side is the source of the River Derwent.

Moorland or moor is a type of habitat found in upland areas in temperate grasslands, savannas, and shrublands and montane grasslands and shrublands biomes, characterised by low-growing vegetation on acidic soils. Moorland, nowadays, generally means uncultivated hill land, but also includes low-lying wetlands. It is closely related to heath, although experts disagree on what precisely distinguishes these types of vegetation. Generally, moor refers to highland and high rainfall zones, whereas heath refers to lowland zones which are more likely to be the result of human activity. Moorland habitats mostly occur in tropical Africa, northern and western Europe, and neotropical South America. Most of the world's moorlands are diverse ecosystems. In the extensive moorlands of the tropics, biodiversity can be extremely high. Moorland also bears a relationship to tundra, appearing as the tundra and the natural tree zone. The boundary between tundra and moorland constantly shifts with climatic change.
