Climb Description

Somport from Jaca

Somport is a picturesque climb in the Pyrenees. The climb from this side begins in the town of Jaca and continues all the way to the border with France; it is mostly very gentle and quite easy to maintain a steady rhythm. The Somport has been used once in the Tour de France and once in the Vuelta a España, but is most famous in cycling circles for forming part of the route for the Quebrantahuesos Gran Fondo.

Fortunately the Quebrantahuesos is run on closed roads and so avoids the main issue with the Somport - the traffic. This is the main border crossing between France and Spain in the Central Pyrenees, and the tunnel at the top ensures that it remains open throughout the year. There are a lot of cars and lorries using the climb and it does significantly affect the enjoyment when you are cycling it.

Other sides
