Free Walking Tours

One of the coolest things I have done on my travels is go on a free walking tour. My experience was with runnerbeantours.com in Barcelona. There are two free tours, Old City and Gaudi, I chose the Gaudi tour. The tour is free and you pay at the end what you think it was worth. It was incredibly informative and you are able to see parts of the city that aren't as obvious to tourists. Another company Sandemans does tours in many countries including the US. http://www.neweuropetours.eu Let me know about your experiences with these type of tours! Any other companies you've toured with? Below are some photos I took on my free walking tour with Runner Bean
