The guide was what made the tour so interesting. Come prepared with alot of questions on anything Plovdiv as the guide will answer anything you can think of. You spend about half the time around the mall and the other half in the old city. You will visit churches and roman ruins but no museums. So the tour is not long and drawn out. The guide can also offer recommendations for day trips around the area, other regions of Bulgaria worth visiting as well as local restaurants, cuisine etc. Well worth the time.
