At the Mirador over Riaño’s dam/reservoir, photographers get wide, high-contrast views of water, dam geometry, and surrounding Picos-style peaks in León. Best light is sunrise for cool reflections and sunset for warm sky gradients; weekdays reduce crowds. Free open-air access from the roadside viewpoint; parking is typically roadside—arrive early for spaces. No entry fees; dress for mountain wind.
