Los Machucos, Mountain pass in Cantabria, Spain.
Los Machucos is a mountain pass in Cantabria connecting the villages of Bustablado and San Roque de Riomiera via a narrow paved road that reaches 921 meters in elevation. The route crosses demanding slopes with steep sections that offer views across the surrounding mountain landscape.
The mountain road was built between 2003 and 2007 with concrete sections engineered to handle the demanding slopes in this region. The project was a significant infrastructure development that connected these remote areas in Cantabria.
A metal sculpture at the summit honors the Pasiega cattle breed, reflecting how livestock farming has shaped this mountain community for generations. The monument shows what animals mean to the people who live and work in these highlands.
The pass demands careful driving due to its steep grades and tight curves, especially during poor weather when conditions can become hazardous. Visitors should exercise caution in rain or snow and drive with full attention, particularly in the winter months.
Professional cyclists tackled this challenging ascent during the Vuelta a Espana races in 2017 and 2019, struggling with the extreme gradients. These racing events brought the pass recognition among cycling fans worldwide.
