When you are visiting a new place and want to find your way around to see the best sights, you may be able to get a tour for free. While finding a free audio tour on iTunes or iAudioguide.com is an option for people who want to figure things out on their own, there are also ways to arrange a personal tour guide without paying a cent. The Global Greeter Network allows you to get in touch with local volunteers who are willing to show you around. You can work out a tour length and area that works best for you. Since you can receive tours from locals this way, rather than just paid tour guides, you are likely to get an insider view from people who are really enthusiastic about the area and can suggest some of the best sites to see.
