For two days after I arrived in Zermatt &mdash the Alpine town in southwestern Switzerland&mdashthe clinical, clockwork precision that the Swiss are renowned for was subjected to one of its sternest tests. The weather had turned a shade inclement, disrupting the planned-down-to-the-minute tour schedules, reducing the sweet-natured folks at Switzerland Tourism to an uncharacteristic mass of apologia. And although the alternative diversions that they lined up at short notice were sufficiently enlivening, the prospect of having to leave Zermatt without ever setting eyes on the region&rsquos showpiece massif &mdash the Matterhorn (4,478 metres), which is celebrating a milestone anniversary this year &mdash proved to be a bit of a mood dampener.
