What is a free tour? Exactly that, you take a tour and are not obliged to pay. The idea is that no matter what your budget is you can enjoy what the city has to offer. Free tours are done by foot, although tours that use the metro and/or bus are offered as well. It won’t be strenuous at all, just a tiny bit of exercise. A free tour is the best way to see Moscow because the guides are the most passionate you can find. You won’t just spend the afternoon walking around alone, but with friendly people who want to show off all the best places in their hometown. Free tours give you real local insight because the opinion of the guides is not influenced by anyone but themselves. Just tip them if you believe they did a good job and you learned something.
