How to drive the old mine road to Collado de la Mina in Sierra de Baza?
Collado de la Mina is a high mountain pass at an elevation of 2,024m (6,640ft) above sea level, located in the province of Granada, Andalusia, Spain. Situated within the Parque Natural Sierra de Baza, in the northern foothills of the Sierra Nevada, the access is via a technical unpaved route. Historically, the road functioned as a specialized industrial mine road, and today it remains a demanding track for high-clearance 4x4 vehicles.

What is the technical difficulty of the road from Las Juntas?
Starting from Las Juntas, the drive to the summit is 14.5 km long. Technically, the road surface is composed of degraded gravel and loose mineral debris from the historical mining activity in the area. Driving this sector requires managing traction on high-altitude meadows (Prados del Rey), where the ground can become saturated and soft during the spring thaw. The 14.5 km ascent demands a vehicle with robust suspension to handle the irregular "calamine" effect often found on these ancient industrial tracks in the Sierra de Baza.
How to manage logistics in the Sierra de Baza Natural Park?
Logistically, Collado de la Mina is subject to the environmental regulations of the Natural Park. Drivers must strictly adhere to the established unpaved roadbeds to prevent erosion of the high-mountain ecosystem, characterized by century-old pine trees. Near the summit, the Refugio Prados del Rey serves as the primary technical landmark. Safety protocols mandate checking the weather window, as snow can block the higher reaches of the pass well into the spring, making the 14.5 km descent back to Las Juntas a high-risk operation due to slippery mud and loose shale.
Mechanical requirements for the Granada mine road transit
The 14.5 km transit requires a vehicle with high-clearance and all-terrain tires to prevent sidewall damage from the sharp rocks typical of the old mine sites. Technically, the descent from 2,024m towards the northern foothills requires precise engine braking management. While the gradients are not as extreme as in the central Sierra Nevada, the isolation of the Sierra de Baza means that mechanical self-sufficiency is a priority. Before starting the climb, ensure the drivetrain is inspected for any fluid leaks, as the high-altitude meadows are ecologically sensitive zones where any chemical spill constitutes a major environmental failure.
