Climb Description

The climb from Gérgal is the most popular ascent of Calar Alto and is the side most commonly used in the Vuelta a España. The climbing here is an acquired taste, as you begin next to a desert and climb through rocky scenery with a few pine trees dotted around providing most of the vegetation.

Nevertheless, it is an enjoyable ride and is particularly special as it is one of very few places in Europe where you can cycle to over 2,000m altitude in the winter. From this side you first climb to the Collado de Venta Luisa; from there turn left and continue the short distance to the observatories that are dotted around the top of the climb.

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

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 throughout the climb - although you may encounter a few cars during the 'rush hours' to and from the observatories.




Alternative Routes

A more scenic alternative to the climb from Gérgal begins in the nearby village of Aulago.

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.
