Whittle Burn is a tributary of the River Tyne. It flows in a roughly southerly direction and joins the Tyne at Ovingham. The burn is about 16 km long with a catchment area of 29 km2. The upper sections of the burn are heavily modified, with an intricate network of watercourses/aqueducts built in the 19th century, which link reservoirs at Colt Crag, Hallington and Whittle Dene. This includes both open water courses and tunnels. The lower sections of Whittle Burn form the is a deep steep-sided valley of Whittle Dene, with an ancient woodland, managed by the Woodland Trust.
