Pico Jano, Mountain summit in Liébana region, Cantabria, Spain.

Pico Jano is a 1,289.7-metre summit in the Iguña valley, on the divide between the Besaya and Pas river basins, within the municipality of Bárcena de Pie de Concha in Cantabria. A geodesic pillar stands at the top, marking that altitude at its base.

The mountain has long served as a navigation point for local communities and was marked with a triangulation pillar. This surveying marker continues to help mappers document the Cantabrian highland territory.

The peak gives its name to the Vuelta a España climb that finished here on 25 August 2022, after a 13.1 km ascent from Bárcena de Pie de Concha with an average gradient of 6.63%. The final stretch from the Mediajo reservoir was paved for the race, and the summit's geodesic pillar stands at 1,289.70 m.

The climb starts in Bárcena de Pie de Concha along a road to the Alsa reservoir, covering 13.1 km to 1,161 m with 869 m of ascent and an average gradient of 6.63%. The final stretch above the Mediajo reservoir was paved in 2022 for the Vuelta a España. The upper section is nearly impossible for a 4x4 because of the steep ground.

From the top, visitors can see the Picos de Europa mountain range and where two major river valleys meet. This vantage point makes the peak a natural viewing spot for the surrounding landscape.
