If you only have time to visit one set of caves on the east coast, this is the one to see.
These caves, near Arta in the north east of Mallorca are a fascinating network of underground caverns, whose weird stalactites and stalagmites conjure up mysterious images of Heaven and Hell. An early visitor was Jules Verne; the caves are said to have inspired his Journey to the Centre of the Earth.
Now that the caves are a sanitised tourist attraction, it is hard to imagine how French geologist Edouard Martel felt when he first stepped into them - dark, mysterious and terrifying - in 1876. In fact they had been known about for centuries. Jaume I found 2,000 Arabs hiding here with their cattle during the Christian conquest and they were later used by hermits, pirates and smugglers. But it was Martel who first studied and chronicled these grottoes, 46 metres above the sea at Cap Vermell, at the instigation of Archduke Ludwig Salvator.
The guided tour comes with special effects and the various chambers are given Dantesque names - Hell, Purgatory, Paradise. The descent into Hell is swifty followed by a 'son et lumiere' display. Stalactites point down from the mouldy roof like daggers, somehow defying gravity. One of the chambers is as large as the nave of Palma Cathedral and the Queen of Pillars, a stalagmite 22m tall, could almost be a Gothic column. It is growing upwards at the rate of 2cm every 100 years, which means that in another 5,000 years or so it will be joined to the ceiling.
You emerge from the caves to a view of the sea, framed by the cavern entrance. Disabled visitors and those with limited mobility will find the staircases in here particularly difficult. All visitors should wear sensible shoes, as the floor can be slippery.
