I went back to the website to check it out. I've never looked for directions because I know where it is. There is a link for the Tennessee Renissance Festival underneath the picture of the castle. Click on it and it will take you to a set of directions with a crude map. If that still doesn't help anyone, let me know.

This is a great venue for highland games. The clan tents are located along a wooded path. They are away from the field events so if you're working a clan tent, you miss out on those.
