        Iceland is not a place for the ordinary tourist. 
        The landscape, first of all, is bare and strange 
        – though many consider it beautiful, too. 
        Then,  the far northern climate is not ideal for 
        tourism. The winter weather is extremely 
        severe and the summers are short and cool, 
        with constant strong winds. The remote 
        location also means that many products have 
        to be imported and so they are expensive. 
        However, the few tourists who do put up with 
        thee difficulties are welcomed by the 
        Icelanders.
