Arthur's Seat is an extinct volcano located in Holyrood Park, Edinburgh, Scotland. It is the highest point in the park, standing at an elevation of 251 meters (823 feet), and offers panoramic views of the city.

The hill is thought to have been formed 350 million years ago during the Carboniferous period. It is named after King Arthur, as it was believed to be one of the possible locations of Camelot. The hill has a number of features, including several rocky outcrops, a loch called Dunsapie Loch, and a number of paths and trails that lead to the summit.

Arthur's Seat is a popular destination for hikers and tourists, and is easily accessible from the city center. The main route to the summit starts from Holyrood Palace and is approximately 2.6 kilometers (1.6 miles) long, taking around 45 minutes to climb. From the top, visitors can enjoy panoramic views of Edinburgh and the surrounding areas, including the Firth of Forth, the Pentland Hills, and the coastline of East Lothian.
