Before you set off
Very steep hairpins and narrow sections can be unsuitable for large vehicles or trailers. Avoid poor weather and allow ample time for the mountain section. Check current road closures, vehicle suitability and weather before travel. Driving time excludes stops and live traffic. The route follows through-roads; all visits off the line are independent optional detours.
