In the first part of this section, the trail was occupied by cows with very impressive horns, which required a few detours through the thicket. It was also very muddy, but it had also rained the day before. After that, however, a beautiful mountain hike with spectacular views is required. Surefootedness and sturdy footwear are necessary. The trail is rarely used, so it's densely overgrown, but marked with red arrows, albeit sparsely. Wear long clothing; there are ticks!

The Covadonga Sanctuary is a Catholic religious complex and an important pilgrimage site. It is dedicated to the Virgin of Covadonga, revered as the patron saint of Asturias. The complex includes several buildings, including the Basilica of Santa María la Real de Covadonga, which was built in the 19th century and houses the statue of the Virgin Mary. There is also a smaller church, the Santa Cueva, which is believed to be the site of the miraculous appearance of the Virgin Mary to the Christian army during the Battle of Covadonga in AD 722. The cave is also the burial place of King Pelayo, who led the Christian army to victory in that battle. The complex attracts thousands of visitors each year, who come to admire the impressive views and learn about the history and culture of Asturias.

On the way from the bus stop to the Lagos, you pass the remains of an old mine - recognizable by the rails that are still in place and an old lorry. The rock face into which the mine shaft disappears is very photogenic.
