Cornwall is the westernmost part of the South West Peninsula, and the southernmost county within the United Kingdom. Its coastline is characterised by steep cliffs and, to the south, several rias, including those at the mouths of the rivers Fal and Fowey. It includes the southernmost point on Great Britain, Lizard Point, and forms a large part of the Cornwall National Landscape. The national landscape also includes Bodmin Moor, an upland outcrop of the Cornubian batholith granite formation. The county contains many short rivers; the longest is the Tamar, which forms the border with Devon.
