Arthur's Seat is the main peak of the group of mountains in Edinburgh, United Kingdom which form most of Holyrood Park, described by Robert Louis Stevenson as "a hill for magnitude, a mountain in virtue of its bold design".[1] It is situated in the centre of the city of Edinburgh, about 1 mile (1.6 km) to the east of Edinburgh Castle. The hill rises above the city to a height of 250.5 m (822 ft), provides excellent panoramic views of the city, is relatively easy to climb, and is popular for hillwalking.
