Climb Description

Puerto de San Lorenzo - San Martin

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.

San Lorenzo is usually closed in winter due to snow; although at times it is cleared and is passable by bike. From April to Novemebr it is nearly always open.
