Before you set off
The mountain road is narrow and exposed. Do not use forestry or reservoir service tracks; check conditions before committing to the crossing. 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.
