Cornwall is a maritime county in southwest England which includes the Scilly Islands. It is bounded on the north by the Atlantic Ocean, on the east by Devon, on the south by the English Channel. The county forms a peninsula 75 miles long at the southwest extremity of England, terminating in Land's End and Lizard's Head, which encircle Mount's Bay. The Scilly Islands lie off this point, 25 miles to the southwest.
The county consists largely of high moorland, broken by numerous granite hills, the highest of which is Brown Willy at 1375 feet. The coasts are bounded by high, steep, slate and granite cliffs. The scenery is wild and picturesque.
The valley of the Tamar forms part of the boundary line between Cornwall and Devon. Other rivers are the Camel, Fowey, and Fal. Good harbors are found on the south coast, but the bays on the north are difficult to access. Bodmin is the county town.
