I read an article today in the Voz De Galicia about a new website by the Spanish Correos that shows detailed route information about the stages of 9 routes, including an FAQ section of "advice from the mailman", and advice from the mail carriers interspersed in the links to each stage of each route. There's some really nice information that's a bit above what I've seen on other sites. Website in Spanish and English.
Each route contains an overview, then information about how to arrive to the starting point (by train, bus, car, and train), and information on different associations affiliated with the route. Within each stage, there's also a brief overview, a few photos, and options to see details about the albergues, private accommodations, and a list of relevant phone numbers (as applicable ... some stages don't have anything listed). And of course, the mailman advice, which is my favorite part. They mention historical sites, places of interest, local festivals, and even specific local food/drink specialties.
The map is actually an interactive Google map to show the route, which allows you to zoom in on the route to really see the detail. Great information!
La Voz de Galicia news article.
El Camino Con Correos link.

Apparently the Correos baggage transfer service is a tremendous success and highly recommended by the local establishments that deal with them (well, the one I asked, at least). There's also a link on this website to all of the information needed to make arrangements:
