Cova de l'Aigua

The Cova de l'Aigua sits on the northern face of the Montgó massif near Dénia, taking its name from the water — "l'aigua" in Catalan — that seeps directly out of the limestone rock inside the cave. Archaeological finds show the cave was used by humans in prehistoric times, giving it a significance well beyond that of a scenic natural curiosity. Its immediate surroundings are equally notable: the rocky north slope hosts a dense concentration of rare and endemic plant species that have placed the area under special botanical protection, making it one of the more ecologically distinctive corners of the Costa Blanca. Access is by narrow, uneven hiking trails on the steep hillside — no wheelchair access, and a degree of surefootedness is required. The reward is a genuinely remote atmosphere shaped by geology, ancient habitation, and endemic flora.
