Lace up those sneakers! Locals and tourists alike can learn much about a place by pounding the pavement. Free walking tours offer an up-close way to experience a new city and sometimes a new perspective on a town you've long called home. We've taken a cross-country approach, spotlighting a variety of free tours that touch on history, architecture, music, sports, recreation, and more. Bring a camera and remember, although no payment is required, tips are always appreciated.
