About Naranjo de Bulnes#

Naranjo de Bulnes, also known as Picu Urriellu, is a prominent limestone peak in the Picos de Europa range of Asturias in northern Spain, reaching 2,519 metres in elevation. The mountain is one of the most recognisable summits in the Picos de Europa and a landmark of northern Spanish mountaineering.

The peak is distinguished by its steep, nearly vertical north face of roughly 550 metres, which has established the mountain as a classic and historic rock-climbing objective. Hiking routes approach the massif from nearby valleys and mountain refuges, while technical climbs use established routes on the walls.

The mountain has long been a focal point for climbers and mountain walkers, and its compact, dramatic profile makes it a conspicuous feature within the limestone massif. It sits within the Picos de Europa National Park landscape, characterised by deep gorges and rugged peaks.

Naranjo de Bulnes is located in the Asturias region of northern Spain, within the Picos de Europa mountain system and the municipal area traditionally associated with Cabrales.

  • Elevation and climbing face: Rises to 2,519 metres above sea level and presents a near-vertical north face of roughly 550 metres that is a classic objective for technical alpine rock climbing.
