Driving the brutal ski station road to Vorabpass in Graubünden
Vorabpass is a high-altitude mountain gap that sits at 2,571 meters in the Swiss Alps, right on the border between the cantons of Glarus and Graubünden. The road to the summit is a raw service track for the Flims Laax Falera ski resort, designed for heavy machinery and chairlift maintenance rather than standard vehicles. It is a punishing drive that takes you through a landscape of barren rock and glacial debris, where the air is thin and the terrain is constantly shifting due to the extreme weather at this elevation.

How difficult is the climb to Vorabpass?
Starting from Flims, the road is a relentless 12.9-kilometer grind with a massive vertical gain of 1,451 meters. The average gradient is a steep 11.24%, but the real killers are the ramps that hit 20%. At this incline, on a surface of loose stones and dirt, maintaining traction is a full-time job. You need a vehicle with a low-range gearbox and a driver who knows how to keep the momentum without spinning the wheels. If you lose grip on one of these 20% sections, the weight of the vehicle and the gravity of the mountain make it almost impossible to get moving again without sliding backwards.
What is the road surface like on the way to the Vorab glacier?
The lower sections of the track are managed dirt, but as you climb towards the glacier area, the ground turns into a mess of loose Alpine scree and jagged rocks. The road is only passable for a very short window at the end of August when the snow has finally cleared. Even then, the melting ice from the glacier above often creates deep ruts and small streams that wash across the track, making the surface unpredictably slick. You have to watch where you put your wheels; one sharp piece of limestone can easily slice through a tire sidewall or damage the steering linkage if you hit it at the wrong angle.
What mechanical precautions are needed for Vorabpass?
This is a high-stress route for any engine. Climbing nearly 1,500 meters in less than 13 kilometers means your motor is under maximum load for a long period. At 2,500 meters, the lack of oxygen means your vehicle is losing around 25% of its power, so the cooling system has to work twice as hard to keep the radiator from boiling over. You must use your gears wisely; staying in a low range is essential to keep the engine in its power band and to provide necessary engine braking on the way down. If you rely only on your brakes during the descent, they will glaze and fail long before you reach the bottom of the valley. Watch out for maintenance vehicles and heavy trucks belonging to the ski station, as they always have the right of way on these narrow, one-lane ramps.
