You cannot miss one of the most curious attractions of the Costa Blanca: its caves. They are spread throughout the province. To the south of the province, we find the caves of Canelobre, in Busot. In the north of the province, in the Marina Alta region, we find the Cueva de las Calaveras, in Benidoleig, with its beautiful stalactites, stalagmites and domes, and the Cova del Rull, in the Vall d'ebo, also offers an immense variety of these unique formations.
