Cenotes (sinkholes) are deep wells with crystal clear water that can be accessed when the roof of a cave collapses. Fed by underground rivers, the cenotes were the main source of freshwater for the Mayans and therefore are considered sacred. They are unique to the Yucatán peninsula, and still to this day, the underground cave system connecting all the cenotes remains largely unexplored. Witnessing the breathtaking beauty of the large clusters of stalactites and stalagmites being mirrored in the crystal clear cool waters is a unique experience. Every cenote has its own particular beauty, and putting on a swimsuit and snorkeling in the pool is an absolutely unforgettable experience. Some tour operators also offer cave diving excursions for very experienced divers.

The “Grand House” of El Castell de Guadalest or “Casa Orduña” was built after the great earthquake of 1644, which devastated the region and demolished the buttress of the castle. It was built by the Orduñas, a family of Basque lineage. They came to the kingdom of Valencia with the Infante Fortuna de Navarra; they later went into the service of the Cardonas, admirals of Aragón. D. Sancho de Cardona received the title of Marques of Guadalest in 1543. As the family enjoyed the complete confidence of the marqueses, they were sent to Guadalest and served as guardians of the fortress and governors of the estate for almost three hundred years.
