As Struay is a fictional place and doesn't really exist like the books, it took quite a while for the team to find the right locations.
In the end the series was filmed a ginormous bit in the Outer Hebrides and a wee bit in the Inner Hebrides.
The final locations are fairly scattered and widespread, and some of them are actually in a ruinous state, but our magical Art Department brought them beautifully, but only briefly, back to life.
If you would like to experience the world in which Katie Morag lives there are many many adventures to be had in any of the Scottish Hebridean Islands, http://www.visithebrides.com/
