Smart business-y types have figured out that there’s some money to be made off of Edinburgh’s architectural splendor, resulting in the vibrant local business of charging people to walk around castles that other people already built hundreds of years ago. Normally, I’m too self-righteous and full of myself to wait in lengthy lines to pay a lot of money to then go walk around something and point at it, but hey, Edinburgh Castle looked really cool, so I gave it a shot.
The requisite tours and exhibits seemed a little underwhelming here. After a lengthy, winding walking tour through the history of the castle's "crown jewels," which resolves a "where did these valuable artifacts end up" mystery with an anti-climatic "at the end of this tour, apparently," I decided to stay outside and just wander around the castle's outer walls. It was pretty satisfying to peek through the small cannon windows and see some views of Edinburgh's skyline, at least. Recommendation: skip the ticket line and admire this from afar.
