A major trading center and the southernmost settlement during Roman times, Volubilis in Morocco is one of the best preserved (and least frequented) ruins of its kind in the world. I found it empty of tourists, not built up, and open in a way that really lets you get up close and see the structures without being behind ten feet of barriers and jostled by crowds. Most of the city is still unexcavated, so the site has a very raw feel to it. I’ve been to a lot of Roman ruins in my travels, but I love this one the best. It’s a lovely day trip away from the crowds and noise of Fez. Entrance is 20 MAD (Moroccan dirhams), or about $5 USD.
