The route connects again with the PR-NA 201 at the milestone where the Vertical Kilometer appears on the right, continuing straight through the panoramic mountain meadow to the popular hermitage of San Donato. Part of the sanctuary is converted into a mountain refuge and is delicious when there is a blizzard or bad weather, as was the case the day we did the route. The geodesic vertex of Beriain is next door, on the rocky tip of a cliff that concentrates the kingdom of abysses and cliffs that float above the towns of the Sakana.
