El Cajer, canyon of La Umbría Nature · Abanilla, Oriental, Murcia Image of Abanilla, not of the place itself. Natural canyon carved by erosion in the hamlet of La Umbría de la Zarza, one of the most rugged sites in the municipality of Abanilla. The río Chícamo flows through it, crossing the Cajer gorge -in a landscape reminiscent of Palestine- with a seasonal flow: abundant during the rainy season and dry in summer.
