As I mentioned in the comments of my castle post, tourist attractions in Edinburgh tend to fall into one of two categories: free, and rather overpriced. Travelers on a budget can focus in on the free sights, as there are plenty. I chose to do a lot of both, because I was in Edinburgh for a long time, and because the average price per attraction is still pretty low if you average the free stuff with the expensive stuff. This post covers my favorites of the free sights.
