Climb Description

Although the Vuelta a España generally chooses to climb from Gérgal, we believe that this is an even more interesting approach to Calar Alto.

The scenery here is sparse and wild. You begin from the edge of a desert and end up at one of the largest observatories in Europe - chosen because of the perfectly clear skies that are common in an area with so little human settlement.

Despite climbing to over 2,000m, don't expect views of snowy peaks and green mountainsides like you would find in the Alps or the Pyrenees. Almeria is the driest region in Europe and the landscape is largely rocky on Calar Alto.

Nevertheless, this is a great climb to do when other monutains of a similar altitude are inaccessible, and the scenery, although something of an acquired taste, is beautiful in its remoteness.

Calar Alto is usually open throughout the year. However, snow is possible in the winter and it can get cold at the top in January and February. The heat can also be a problem in July and August, with temperatures often in excess of 35°C and very little shade to be found.

Calar Alto is extremely quiet and peaceful to ride





Roads & Traffic

The road is in very good condition throughout and is enjoyable to both climb and descend on a road bike.

There is very little traffic on the road. Once you have crossed the motorway, and certainly once you have passed the village of Aulago, you are unlikely to see more than two or three cars during the entire climb.

Alternative Routes

The most popular way to climb to Calar Alto begins from Gérgal - this is the route mostly chosen by the Vuelta a España.

On the northern side there are also three more great routes. An easier one from Serón and two challenging routes from Tíjola and via Las Menas.
