There are passes that are remembered for their toughness and others for the landscape they offer. Las Crucetas belongs to the latter. When you stop your bike and look back, it's inevitable to think that every meter of ascent has been worth it. In that instant, the effort disappears and only the satisfaction of contemplating a mountain range that seems to stretch to infinity remains.

Notice... The vegetation changes noticeably as you gain altitude. Aleppo pine predominates, accompanied by holm oaks, Pyrenean oaks, and a undergrowth of rosemary, thyme, and lavender. If you do the route in spring, the aroma of Mediterranean plants permeates the entire pass.

The port of las Crucetas, located at an altitude of about 1300 meters, is one of the most important natural passes between the Salobre river valley and the Sierra de Alcaraz mountain range. From its summit, the road makes its way through extensive pine forests and offers magnificent panoramic views of a landscape shaped over millions of years by erosion. For the cyclist, reaching this pass means leaving the gentle hills of La Mancha behind to definitively enter the mountains, where the air is cooler, the silence deeper, and nature takes center stage.
