You could make the most of your time and resources by taking an Edinburgh hop-on, hop-off bus tour and hopping off near the castle. The Royal Mile walk from the castle to the Palace of Holyroodhouse is a must-do where you can admire the impressive architecture and star attractions of the city. Waverly station is also a walking distance from the castle and is Edinburgh’s main station. If you want to take a bus, then the Airlink 100 express bus runs from the airport to the city centre. It takes 25 minutes to reach Waverley Bridge, next to the main railway station. We also advise that you book the castle ticket or tour with roundtrip transfers included in the package in order to enjoy a convenient and hassle-free experience.
