The Camino is a well-known medieval pilgrimage in the Catholic faith that attracts a wide range of people to walk it almost continuously.
Although the majority of pilgrims are Catholic, or have some other kind of Christian faith, surveys show that around 16% of walkers have no faith at all and walk it for other reasons, including just to see if they can.
The most popular long version of the route from SW France across to the NW coast of Spain takes about 5 weeks to walk.

Walkers who set out together often end up spending time on the Camino walking apart or with strangers. This raises a practical communication issue: how to communicate your plans, discoveries or just your state of mind to someone ahead on the road, or to leave messages behind you without actually turning back yourself.
One way to handle this as a communication problem when you need to get a message to someone else is to Tell A Passing Stranger.
We know a good deal about the medieval pilgrimage route because of the existence of the Codex Calixtinus a guide to the route written for medieval pilgrims in the 12th century and a relatively early example of the Travel Guidebook
