If you want to know something about the Vega Baja, then the Convega website is a great starting point.
Apart from a host of general and specific information about the region, the site makes good use of Google maps, to show you places of interest in 27 different municipalities. Included in each section is information about a whole range of facilities in each town including restaurants, places to stay and even where to fill up with diesel.
Although there is a button to change the language to English, the site explains that this page is under construction. Still, as it stands, the site provides some useful practice with your Spanish.
