Known as the "Garganta Divina", this route between Cain (Leon, Castile and Leon) and Poncebos (Asturias) offers you the opportunity to walk between mountains that rise more than 2,000 meters above the bottom of the imposing gorge dug by the Cares River. You will see mythical peaks, cross bridges that connect both sides of the gorge, go through about 70 tunnels carved into the rock and witness an amazing natural spectacle.

The Ruta del Cares is exceptionally popular, especially the first 6 kilometers from Cain, offering spectacular views of the gorge. Another highly regarded option is the Cares Gorge (Garganta Divina) itself, known for its trail carved into limestone along the Cares River, featuring numerous tunnels and bridges. These routes are celebrated for their dramatic landscapes within the Picos de Europa National Park.
Yes, the Arenillas Blowholes (Bufones de Santiuste) provide a dramatic coastal spectacle. These karstic formations, located in a neighboring municipality, create powerful jets of water up to 40 meters high when ocean waves force air and seawater through fissures in the limestone cliffs. It's an impressive natural phenomenon, particularly on stormy days.
The Picos de Europa National Park, where many of these natural monuments are located, is rich in biodiversity. You might spot various species typical of an Atlantic ecosystem, including roe deer, chamois, and diverse bird species. While Iberian wolves are present, they are more elusive. The lush environments of gorges like the Cares and Casaño rivers support a vibrant natural habitat.
For a more serene and less crowded experience, consider the Foces del Río Casaño (Gorges of the Casaño River). This enchanting route follows the crystal-clear Casaño River through dense vegetation, including ancient chestnut trees and moss-covered rocks. It offers a magical atmosphere and a deep connection with nature, often appealing to those seeking tranquility away from more popular trails.
The Cueva del Llonín, located within Peñamellera Alta, is an extraordinary example of Paleolithic cave art, declared a Heritage of Mankind. It contains over a hundred identified Paleolithic figures, including animals and red signs, showcasing ancient human creativity.

The Foces del Río Casaño is generally considered easy to moderate, with many shaded sections, making it appealing for families.

The clear streams, like the Crystal-clear stream near the Cares River, also offer opportunities for cooling off on hotter days, which can be enjoyable for families.
The spring and autumn months are generally ideal for visiting, as the weather is milder and the landscapes are particularly vibrant. Spring brings lush greenery and blooming flora, while autumn offers stunning foliage. Summer can be popular, but trails might be more crowded, and temperatures higher. Winter can be beautiful but some higher-altitude trails may be inaccessible due to snow.
Visitors frequently highlight the spectacular scenery and the immersive experience of walking through dramatic landscapes. The carved pathways and tunnels of the Cares Gorge, the powerful jets of the Arenillas Blowholes, and the serene, enchanted forests of the Foces del Río Casaño are often praised. The sense of being surrounded by towering mountains and pristine rivers is a common theme in visitor feedback.
