Pic Negre is a high mountain pass at an elevation of 2.643m (8,671ft) above the sea level, located in the Pyrenees on the Andorran-Spanish border. It's one of the highest mountain roads of the country.
The track to reach the summit, a dirt gravel road, starts in Sant Julià de Lòria, the main town of the parish with the same name, which at 908 m is the lowest settlement in Andorra. The road is totally impassable in winter.
The weather on this zone is harsh and highly unpredictable and it does not take much time for the bright sun shine to change over to moderate to heavy snow fall. A sudden drop in the temperature, even in summer, can trigger winter-like conditions. This trail passes through remote areas, so you need to be prepared. This route is not suitable for normal cars.
If you dare to take the risk and travel along this dusty and bumpy route, then make sure to be driven by someone who has experience of the road. It has a well-deserved reputation for being dangerous because of unpredictable snowstorms and blizzards, and driving under these conditions, can be extremely challenging. 4x4 required.
