El Castellet perches at 1,050 meters on a rocky outcrop called Penya del Castellet, offering commanding vistas across Castell de Castells and the Guadalest valleys. This Muslim-origin fortress features two distinct defensive sections with surviving semirruined wall sections, cisterns, and lower tower remains. Conquered by James I in 1254 and later controlled by the Order of Calatrava, the castle was likely abandoned early in the Christian period following Morisco expulsion. Accessible via marked hiking trails with white and yellow blazes through Gaspar ravine, the site provides archaeological interest and connects to the GR 330 Costa Blanca Interior long-distance hiking route.
