Fasten your seatbelts!. Splügen Pass, Switzerland

With their twists and turns, record heights, and breathtaking vistas, mountain roads are not for the faint-hearted. Pictured here is the historic Splügen Pass, which winds its way through the Lepontine Alps, on the border of Switzerland and Italy. Although its modern version was built between 1818-1823, the Splügen Pass existed in some form as far back as Roman times. At 6,936 feet high, it is one of the highest paved roads in Europe, with 51 marked hairpin bends. It is closed in winter but, if spectacular mountainside views and picturesque lakes tickle your fancy, you can enjoy this ascent between June and mid-October. Have we 'peaked' your interest yet?
