We went to the Edinburgh Castle located in Edinburgh, Scotland. And we had a really great time. The castle is huge and a tour guide is recommended, however we chose to go with the audioguide. I'm still not sure if we made the right decision, though we definitely saved lots of money that way. The history that you learn there is fascinating and the views that you can see from the castle of the city, is really beautiful. It's definitely a place to go when you're in Scotland. The Museum Of War located in the castle is probably the most interesting part. Be sure not to miss that when going.
