Through the CASLS (Center for Applied Second Language Studies) newsletter I learned about a fairly new online magazine totally in Spanish called VeinteMundos. Here’s the information from their site: 
Journalists from Spain and Latin America write interesting reports and articles about everyday life and culture in their homelands. Alongside, Latinos tell us about their experiences in Europe, and Europeans and Americans about their experiences and travels in Spain and Latin America –all in Spanish, of course.
The texts are accompanied by key vocabulary and are written in varying degrees of difficulty, so that you can practice and refresh your Spanish in an efficient and enjoyable way.
An issue is released every month, free of charge, which includes a PDF version of the magazine, an audio version and a vocabulary list. Also, there are resources for teachers such as teacher guides, vocabulary lists, mp3s and more.
