The pilgrimage is centered upon Santiago de Compostela, a city in northwestern Spain where tradition holds the body of Saint James, apostle of Jesus Christ, is buried. Saint James traveled to Spain to spread Christianity before returning to Judah where he was martyred. His Spanish followers are said to have taken his body back to Spain.

The Emilio Estevez/Martin Sheen movie The Way is probably the best introduction to the pilgrimage. However, there are plenty of books and movies, both secular and religious, which document the pilgrimage itself day by day and the over all experience.
One of the most common threads shared about The Way is the social experience. Many people meet up and form bonds which help define the trip. The below movie does a good job of showing the progression of The Way while also keeping the important human element in a central place.
There is also a documentary on one person's spiritual journey, spiritual development being another major theme of The Way travel media, while doing the walk.
To be fair, however, travel writer Francis Tapon warns that much of the pilgrimage is on paved surface and near traffic. [Note: bad language and historic inaccuracy in the article]
