Kirkwall is the largest town in Orkney, with a cool maritime climate that's cooler than the rest of the UK in summer. It's known for its historic St Magnus Cathedral and as a hub for ferries to various destinations. The town's name comes from the Norse "Kirkjuvágr," meaning "church bay," reflecting its origins in the 11th century. While in town, wander the small streets with cafes and small shops. Take time to explore St Magnus Cathedral, Orkney Museum and the ruins of the Earl's and Bishops' Palaces.
