It was an awesome way to spend some time. We were with a guide, who provided a thorough history of every structure within the site. His knowledge of Volubilis was extensive. But this is a place one could visit just for the serenity and a self-guided tour. Most of the important structures have a sign nearby providing a bit of context. Nothing like you will get from a guide, but at least some context. The old mosaics are amazing. I wish they would protect them better.
