The town of Berria has been built on an isthmus that was formed by dueling north winds. The beach here is a popular day tourist destination.
At the end of Berria, the camino splits. This is one of the rare points where the official camino might not be the best option. Where the main road turns left at the end of town, the camino turns right onto a trail which climbs 100m up to the top of the El Brusco headland. Although this climb affords excellent panoramic views from the top, its steep sandy terrain is not for the faint of heart.
The alternative is to follow the road to Noja.
The official camino over the Alto de Brusco is straightforward. To follow the alternative along the road, turn left at the bend to follow a pedestrian path past the first roundabout. At the second roundabout bear right to follow the CA-141 in the direction of Somo. There exist several variants of the camino along this stretch, which may accidentally take you away from Noja and to San Miguel de Meruelo.
All of these options require you to turn left off of the CA-141 so if Noja is your destination, keep on the main road and ignore all left-hand turns. When you do leave the CA-141 it will be to the right and is marked Helgueras 2km.
If neither Helgueras, Noja, nor Castillo are on your agenda you can follow the left facing arrows and continue directly to San Miguel.
