There’s no better way to explore a new destination than at ground level—and walking speed. The best walking tours go exactly at your own pace, one foot in front of the other, to the precise places you want to go. Walk the northern border of England along Hadrian’s Wall, or give Vermont’s Long Trail—the inspiration for the Appalachian Trail—a spin. No matter the continent, guided walking tours can take travelers to remote locations or better contextualize familiar ones.
