The descent ends at the Col Col, a crossroads of roads and forest tracks where the colored posts of the GR-90 long-distance trail appear. The route continues along the path towards Purujosa. The signage is new and impeccable. The path shortcuts the hairpins of a forest track and descends directly to the Fuente del Col, a true oasis in the mountain because it is the only place with guaranteed drinking water. In the spring area there is a fountain with a trough, ponds and irrigation ponds.
