Collado del Álamo: A steep gravel climb in Sierra Nevada
Collado del Álamo is a demanding high-mountain track located in the heart of the Sierra Nevada National Park. Reaching an elevation of 1,729m (5,672ft) above sea level in the province of Granada, this unpaved route serves as a balcony over the highest peaks of the Iberian Peninsula. However, the technical nature of the climb and the extreme gradients make it a road where mechanical reliability and tire traction are far more important than the surrounding scenery.

How is the climb from Puerto El Purche to Collado del Álamo?
The journey begins at Puerto El Purche (also known as Collado del Muerto) and covers 9.9 kilometers of rough mountain terrain. The road is entirely unpaved and characterized by a constant change in elevation, with a total gain of 470 meters but also significant descents of over 220 meters. The ferro of this route is the surface; as seen in the white, dusty tracks typical of the Granada mountains, the loose stones can make the 15% ramps extremely difficult for vehicles without four-wheel drive. Maintaining a steady pace is essential to avoid digging the tires into the soft edges of the track where the mountain slope drops away sharply.
Why are the 15% gradients of Collado del Álamo a technical risk?
While the average incline might seem manageable, the Collado del Álamo features specific sections where the gradient hits 15%. On a gravel and dirt surface, these ramps test the cooling system and the torque of your SUV or all-road vehicle. If you attempt the climb during the hotter summer months, the thin air and the lack of shade can push engine temperatures to the limit. Precision steering is required to avoid the larger rocks that often wash down onto the road, and you must be prepared to manage the vehicle’s weight on the steep descents, where the loose ground makes braking less effective than on asphalt.
Is snow a persistent hazard on the road to Collado del Álamo?
Due to its location within the Sierra Nevada range, snow is a major factor for most of the year. The road is generally only passable from late spring to early fall. Even in May or June, shaded corners of the track can hold deep drifts that make the pass impassable for standard vehicles. Navigating these high-altitude roads requires checking the local mountain reports; a sudden storm can turn the dusty track into a slippery mud slide in minutes. Because the road is narrow and lacks any form of safety barrier, attempting the drive in low visibility or after a recent snowfall is not advised due to the risk of sliding off the shelf.
What are the operational requirements for driving Collado del Álamo?
This is a high-mountain environment where self-sufficiency is key. The proximity to the Mulhacén and Veleta peaks means the weather can shift violently. Before engaging with the 9.9 km track, ensuring your tires have enough tread to handle loose shale and that your spare is fully functional is mandatory. The Collado del Álamo is a road that demands respect for the Sierra Nevada's verticality; it is a technical transit where the mechanical integrity of the car and the driver's ability to read the unpaved surface are the only guarantees of reaching the summit and returning safely to the lower valleys.
