Along windy mountain roads, past powder-laden slopes and glitzy vin chaud stops, this route that runs around the border of Switzerland and into France is a snow-sure adventure for serious ski folk. And beyond the peaks and high-altitude playgrounds of one of the most glamorous stays in St Moritz, we’ve threaded in a pit stop through Zurich (popping into the Fraumünster church to see the Chagalls is worth every stiff leg), down through Bern and into the French hills for nights of sleep at hotels that help to shut off, slow down and fuel up. Just make sure you have the right tyres for this one.
