Climb Description

Puerto de San Isidro is a long climb through the Redes Natural Park. It begins by climbing very gently through several villages along the River Aller valley. After passing Felechosa, the climb starts for real, with the highligh being the spectacular series of hairpin bends which begin around 7km from the summit. San Isidro is an even better descent than it is a climb - with wide, well surfaced roads making for enjoyable riding.

The climb has been used numerous times in the Vuelta a España; notably in 2008, when Alberto Contador won a stage finish to the ski station at the top of the climb.

San Isidro is usually kept open throughout the year to enable access to the ski resort. In winter it can be very cold though so make sure that you come suitably prepared.

Roads & Traffic

The road surface is in very good condition.

The amount of traffic varies on the climb. The first half is more busy and by the top it is very quiet. At no point, however, it is especially bothersome.

Alternative Routes

Puerto de San Isidro can also be climbed from the east from Isoba. This is a short and gentle climb, with very little elevation gain.
