With almost a thousand metres of caves and six submerged lakes this is not a place for the claustrophobic. Its eerie depths are spectacular with stalagmites that create an almost cathedral-like atmosphere. The high light of the visit is listening to a string quartet playing on a boat on one of the lakes. Visitors may also take a trip across the water before hey leave the caves if they so wish. For more information check out www.cuevasdrach.com. Near at hand is the aquarium of Porto Cristo, a fun trip for the children.
