The Mundo has a length of 150 km and a drainage area of 766 km2.<ref name="chseguara.es-data">EL RÍO MUNDO, PRINCIPAL AFLUENTE DEL SEGURA auf chsegura.es (retrieved 2012-12-8)</ref> It receives most of its tributaries in its upper course. They include the Rio de la Vega, the Rio de los Vadillos and the Rio de Bogarra.

At the Talave reservoir the Mundo receives additional water via a 250 km long aqueduct coming from reservoirs of the Tagus river.<ref>Juan B. Marco, R.

The Mundo river is known for its picturesque source (Reventón del Rio Mundo), which is considered one of the world's most beautiful river sources. It originates from a cave in the middle of a tall cliff and forms a waterfall with a height of almost 100 meters. Subsequently, it forms a series of smaller cascades and pools. The cave itself is about 15 meters wide and 25 meters high and constitutes the end of a large cave system under the Calar del Mundo.<ref>Rolf Neuhaus: Wann birst die Welt? at faz.net on 2012-12-5 (German)</ref>
