Climb Description

Puerto de San Lorenzo from La Riera is set entirely within the boundaries of the stunning Somiedo Natural Park. The scenery here is spectacular, with the mountains home to the widest variety of mega-fauna anywhere in Spain. While you almost certainly won't see the bears, wolves or lynx which inhabit the park, you will see horses and cows which are often standing in the road - particularly towards the top of the climb.

It is a tough climb, with steep gradients throughout, and it has become a favourite of the Vuelta in recent years, where it used to soften up riders before a stage finish on nearby Angliru or La Farrapona

Puerto de San Lorenzo is usually open throughout the year, although short term closures are possible in winter.
