Look beyond the water, Cares Chanel or Canal del Cares, and then up at the narrow pathways carved into stone to see one of the most beautiful hiking adventures in Spain. This trek is along the Cares River and through the Cares Gorge in Picos de Europa National Park. The Cares Gorge has many names like “Divine Gorge” or Garganta del Cares, but everyone agrees on its rugged beauty. Photo #1 by David Valije

Care Gorge Route: Narrow paths with steep cliffs stretching up over 6,500 ft (2,000 m) on one side and the Cares River far below on the other side. Photo #2 by Raúl González

Walk on the wild side, Cares Gorge in Spain. Part of the footpath was once nothing more than a goat trail, traveled by animals and shepherds long ago. This ancient route provided the only communication between the villages of Caín (León) and Poncebos (Asturias) during snowy winters. In the 1940s, the electricity company Viesgo carved a trail high up into the craggy gorge walls; it was a maintenance path to service the Poncebos hydroelectric canal that runs between Cain and Camarmena along the Cares River.

Cares River Route in the heart of Picos de Europa National Park is 9.321 miles (15 km) long one way. The walk takes an estimated 3 to 4 hours one way, or 6 to 8 round trip. Photo #4 by Max Westby

Today people can appreciate the trek with gorgeous landscapes, but many men lost their lives while digging into limestone rocks to create the Cares Route, or Ruta del Cares. Photo #5 by Jose Luis Canale

Crowds walk the path through Cares Gorge. It is advised not to take the route “during the month of August or summer during the weekend due to the large crowds that occur.” Photo #6 by _Lares

People with vertigo may not want to take the “La garganta divina (Asturias – León)” hike, but everyone should bring plenty of water to stay hydrated as there is not much shade. The footpath is about 8 feet wide in places, but all adventurers should keep an eye out as rock-slides are always possible. Photo #7 by Raúl González

If you go early and avoid weekends, holidays and summer, you might be like this lone hiker on the route? Yet spring and autumn are noted to be the most beautiful times of the year to make the trek. Photo #9 by Ramón Pérez Niz

Adventure at Garganta del Cares. Paraphrasing this Hiking in Spain book: Despite this classic Picos walk being almost too popular, it’s earned this popularity for a very good reason. It’s well worth braving the maddening crowds to get a piece of the action. The walk, though long, is easy and is undertaken by all ages and walking abilities. Photo #11 by Senderismo Sermar

The photographer noted, “In the Asturian part of the Ruta del Cares, a few meters from the border with León, I found this natural setting :-)” Photo #12 by Jorge Cabrera

“Somewhat complicated,” wrote the photographer. There are some places along the gorge route where the river is 650 feet (200 meters) below. Photo #15 by Ramón Pérez Niz

Trickling water at Garganta del Cares. Although many people choose to start the trail in Caín and end in Poncebos, adventurers can start the walk from either town or hike to one and round trip back again. Photo #16 by Ramón Pérez Niz

Hikers on “The Divine Gorge” route. The Cares canal was built between 1916 and 1921, but it took another couple decades before a footpath was carved through the limestone as a maintenance path for a hydroelectric dam. Photo #17 by Erik Daugaard

Walkopedia scores Cares Gorge (Garganta del Cares) as an 87 mostly for its beauty, but “crowded at high season and at weekends” was a noted negative. Photo #18 by Senderismo Sermar

During the holidays and summer, the trail is traversed by thousands of people as if it were part of a main street in a big city instead of miles of trail out in nature. Photo #30 by ccdoh1

Cares Gorge Fauna, Picos de Europa. The photographer added, “Don’t annoy the natives!” There were quite a lot of goat photos along the route, some noted to take care if goats above you on the rocky mountains are descending as this too could potentially cause falling rocks. Photo #31 by NicolaJH

According to Wikipedia, “The Cares is known because of the narrow and spectacular canyon it forms when passing the Asturian Massif, there is a famous trekking path known as ‘Ruta del Cares’ that runs along the river, being one of the most remarkable Asturian geographical attractions. The Cares river is also known because of the quality of its salmon.” Photo #34 by Ramón Pérez Niz
