This ride to the Puerto de Panderruedas begins in Vegacerneja, which lies a little north of the Embalse de Riaño. With only 158 climb effort points and 355 meters in altitude this is an easy climb. Over the first 7 kilometers, when we head in the direction of the Puerto del Pontón on the national road, the elevation gain is very small (average 2.1%). At the turnoff towards the Panderruedas 4,5 kilometer remain tot the pass. These are a little steeper, with a steepest kilometer of 7.3%, than before the turnoff. First the road leads through the forest, so views are rare but gradually more views of the surrounding mountains emerge. At the pass itself two magnificent mountain massifs of the Picos de Europa dominate the sight.
