'Antarctica is beyond fashion,' says Glen Donovan, tour operator to Jade Jagger and friends. It is an otherworldly place of silent, desolate whiteness, where glacial lips slink between bald and shadowless slopes, the only colour from cobalt icebergs and blue veins frozen deep inside towering ice cliffs. There's no Versace, no McDonald's, no polar bears (that's the Arctic, and a faux pas you will want to avoid). A wilderness twice the size of the US - unowned, uninhabited bar the odd lonely scientist - Antarctica remains one of the safest places in an uncertain world, a virginal space where the mobile phone blessedly ceases to work. Put simply, it is a place that makes you glad to be alive.
