I want to recommend their “Prague Explorer Tour – All Inclusive” and the “Underground Walk”. These tours are a definite MUST DO!!! I would suggest requesting Bryan as your tour guide. He is a wealth of knowledge whether you are interested in a historical, architectural, cultural or sociological perspective of Prague. The Explore Tour is highly comprehensive covering all the neighborhoods and historical sites. You really must do this tour when you first get to Prague so you then can take advantage of the local tips for restaurants, shops etc and bookmark places of interest you may wish to revisit on your own leisure!
