There are some very good online tools to help you find albergues along the different routes.
The Eroski Planning site has information about albergues on a variety of different camino routes. To check out their albergue listings, as well as monuments to see along the chosen route: Click Here
My Camino Bed is a site that provides wonderful albergue information on the Camino Frances. You can search by maps, or by the stage you are on. There are stages defined but when you click on the stage it lists all the towns in that stage and you can further zero in to a specific town, and then to the albergues within that town, and finally you can click on each of the albergues listed to get more specific information about the amenities of the albergue.
