Picos de Europa



The “Big Trek” tour is suitable for those Hill Walkers who enjoy trekking “hut to hut” and challenging walks at higher altitudes over tougher longer routes.  Ideal for experienced more top walkers.

The Central or Urrielu Massif of the Picos de Europa is with no doubt, the wildest and spectacular scenery in the National Park. The highest peaks of the National Park are in this massif, Torrecerredo (2,650 m) and its iconic mountain, Naranjo de Bulnes or Pico Urriellu.
·         Sleep to the base of the iconic peak of Naranjo de Bulnes
·         Hike a stunning landscape affords unique views in the heart of the Picos de Europa
·         Experience a breath-taking part of the moon scenery of this National Park.
·         Enjoy the best sunset in Picos de Europa, sleeping in Collado Jermoso Refuge.
·         See a rich and varied fauna. Among other species, there are Chamois, Griffon vultures, Eagles, etc.


This tour gives you all of that; the walking is one part of it, the cultural & environmental experiences are the others.

Day 1: FROM VALCAVAO TO COLLADO JERMOSO REFUGE. Gradient: + 700m – 400m Distance: 8 Km Duration: 4-5 hours

Meeting point in Cangas de Onis. Transfer to Pandetrave mountain pass and then by track to Valcabao. Today we start with a wonderful walk that goes from Valcabao to Collado Jermoso Refuge by the Canal de Pedabejo, walking near the spectacular Vega de Liordes and along the cliffs of Colladinas until arriving at Collado Jermoso Refuge, our first stop and overnight. We rest and look forward to watching the fabulous sunset with wonderful views of the Valdeón valley and the Western Massif. Dinner and overnight at the refuge.

Day 2: FROM COLLADO JERMOSO REFUGE TO URRIELLU REFUGE. Gradient: + 800m – 850m Distance: 10 Km Duration: 6-7 hours

We leave the Refuge to the Collada Ancha and Tiro Casares to reach the Cabaña Verónica Refuge. From here, we descend to Horcados Rojos with incredible views of Naranjo de Bulnes and descend to the Jou de Los Boches by a steep and exposed slope, not suitable for people with vertigo. We cross the moonscape of the Jou of Los Boches and Jou sin Tierre until arriving at the Urriellu Refuge. Dinner and overnight stay at the refuge.

Day 3: FROM URRIELLU REFUGE TO CABRONES REFUGE. Gradient: + 700 m - 550 m Distance: 6 Km Duration: 5-6 hours

We start by leaving behind us the west face of the iconic Picu Urriellu, walking up for “Corona del Raso”. Now we have a short scramble through “Brecha de los Cazadores, which takes us closer to the “Horcada Arenera (2,283 m)”. Now we can ascend a nearby summit across complicated terrain and karstic holes, known as “Jous” in Picos de Europa. We continue until Cabrones Refuge, in one of the wildest and spectacular places of the Picos de Europa. Dinner and overnight stay at the refuge.

Day 4: FROM CABRONES REFUGE TO PONCEBOS. Gradient: - 1.780 m Distance: 8,5 Km Duration: 4-5 hours

We finish this incredible Trek with a hard stage because of the huge slope of descent which is quite technical.  In the first part, you go through aerial cornices with the help of fixed ropes and delicate steps until you reach the “Cuesta del Trave”. From here a very steep descent towards the “Majada de Amuesa” to reach the town of Bulnes. After a rest and meal in the village, a final descent down the “Canal del Tejo” to Poncebos.

The Trekking is done. In Poncebos, the vehicle is waiting for us to transfer to Cangas de Onis.

    We have walked in several countries both independently (couple) and using guides with larger groups over 10 years. This “Big Trek” offering from Rumbo a Picos was the best. Challenge and exhilaration experienced as we crossed the high Picos over 4 days – 3 overnights in huts, in itself a very enjoyable experience. Our guide was the very professional Ernesto who took great care of everyone in our group of 5 .. strongly supporting as required. He was also great fun. All communications prior to the trip were excellent. Transport and arrangements during the trip were also great. Muchas gracias Ernesto y Josemi .. Pat & Nuala
