Rome Walking Tours
 

Any suggestions on good companies to contact for a walking tour?
I'd like to cover Vatican and other major attractions. We will be there for 4 nights.

I often book people with Context, but they aren't cheap. They have a variety of choices.

I did an architecture tour with Context last spring and really enjoyed it.

I had an amazing tour with Context at the vatican. I would always recommend them. I am trying a new company in sept ....Throigh eternity. I liked the sound of the underground tour they offer and they get great reviews on Trip Advisor.

Context is wonderful and worth the high price, but if you don't have the budget for that, Through Eternity is also great :)
