Driving the service road to Collado de las Yeguas: 2,859m in Sierra Nevada
Located in the heart of the Sierra Nevada range, in the province of Granada, the ascent to Collado de las Yeguas is a journey to the limits of vehicle performance. Reaching an elevation of 2,859m (9,379ft) above sea level, this mountain pass is one of the highest navigable points in the country. It is a functional service road for the ski resort, where the extreme altitude and the raw terrain of the high peaks create a driving environment that offers no room for error.

Where is Collado de las Yeguas?
The pass is situated in the autonomous community of Andalusia, within the high-altitude desert of rock that forms the upper reaches of Sierra Nevada. The track begins where the paved A-395 ends its public transit, heading into the restricted service areas of the ski station. This is a world of shale and granite, positioned high above the clouds of Granada, where the weather can shift from intense sun to a freezing blizzard in a matter of minutes. It is officially ranked among the highest mountain passes in Spain.
Is the road to Collado de las Yeguas paved?
No, the road to the summit is a raw mountain track made of loose stones and gravel. It is primarily a chairlift access trail designed for heavy maintenance machinery. The surface is unstable, and as you climb higher, the rocks become larger and sharper. You absolutely need a high-clearance 4x4; a standard vehicle will simply spin its wheels or suffer terminal damage to the undercarriage. The track is only clear of snow for a very narrow window, usually at the end of August, and even then, the ground remains soft and prone to erosion.
How long and steep is the drive to the summit?
Starting from the paved A-395, the climb is only 5.2 km long, but it is one of the most punishing stretches of road in the region. The incline is relentless, featuring several ramps with gradients up to 20%. At nearly 2,900 meters, your engine will be struggling with the lack of oxygen, losing significant power just when you need it most to clear the steepest, rockiest sections. You must maintain a steady throttle and use your gear range carefully; if you lose momentum on a 20% slope of loose rock, restarting the vehicle without digging yourself into the shale is a major challenge.
What are the main hazards of this high-altitude road?
The combination of extreme verticality and the risk of altitude sickness makes this drive particularly hazardous. The air is thin, affecting both the driver's concentration and the vehicle's cooling efficiency. The weather is a constant concern; high winds on the ridge can buffeting the vehicle, and the lack of any safety barriers means that a single mistake on the narrow path could lead to a fall. This is an inaccessible and lonely route where a mechanical failure means you are stranded in a high-alpine environment with no cell service and no easy way to get a recovery vehicle up the 20% ramps.
Can I drive to Collado de las Yeguas year-round?
Absolutely not. For most of the year, this road is buried under meters of snow and serves only as a ski run. It is one of the highest roads of the country and is only accessible to specialized vehicles for a few weeks in late summer. Even in August, you must check the forecast for Sierra Nevada; if there is any hint of rain or storm, the track turns into a slippery mess of mud and sliding rocks that will defeat even the most prepared 4x4. Always carry emergency supplies and ensure your tires are in perfect condition before attempting this ascent.
