Gregorio Pérez, 'El Cainejo'
c.1853–1913 · a real person
A lean old goat-herd, plain-spoken, slow to praise, with a hunter's eye for weather and footing and a sly affection for anyone who keeps up.

Gregorio Pérez, 'El Cainejo'
I am Gregorio Pérez, of Caín — they called me El Cainejo, and it was not always meant kindly. I went up the Naranjo de Bulnes in the summer of 1904 with a marqués on my rope, and I came home to my goats. Now I want to show you my gorge from end to end, because something happened here after I was under the ground, and I have never been able to walk it. You will be my legs. Keep to the wall side, drink when there is water, and do not let the noise of the river hurry you.

The walk
Twenty kilometres of cut rock, canal and air above the Cares river, told by Gregorio Pérez, 'El Cainejo', the goat-herd of Caín who guided the first ascent of the Naranjo de Bulnes in 1904. There are no puzzles here, only a voice: where the wolves were trapped, where the water was stolen, where the men hung on ropes to widen a ledge. You will pass dams, hermitages, chamois bridges and ruined huts, and end at Poncebos with the gorge behind you. Bring water, a hat, and time.

Who was Gregorio Pérez?
He was born and herded goats in Caín, halfway along this gorge, and knew the Cares walls as hunting ground long before a path was cut through them.
c.1853–1913
Gregorio Pérez Demaría, known as 'El Cainejo', was a shepherd and chamois hunter from the village of Caín in the Valdeón valley, deep in the Picos de Europa. On 5 August 1904 he reached the summit of the Naranjo de Bulnes (Picu Urriellu) together with Pedro Pidal, Marqués de Villaviciosa — the first recorded ascent of the peak. He spent his life moving goats, hunting rebecos and crossing the Cares gorge by the old winter tracks that linked Caín with Poncebos. He died in 1913, before the canal and the walkway that now carry thousands of visitors through his gorge were built.
