En Pangea Routes A little over a year ago we learned about a project called Empty Mountains, a new proposal was born cycle route in an area that we have always loved, the Universal Mountains. The route includes territories of the Sierra de Albarracín in Teruel, the Serrania de Cuenca and the Alto Tajo de Guadalajara. This entire territory has an area similar to the island of Mallorca. Our Route of the Cid, our tours through the Sierras de Albarracín or Alto Tajo had already shown us the possibilities of these territories.
