Cudillero is a small, picturesque fishing port which sits on the side of a mountain. Outstanding are its hanging houses with eaves and brightly-coloured windows perched on a horseshoe of steep cliffs around the port.

It has many routes with viewpoints, among which it is worth mentioning the walk to the lighthouse, La Garita, La Atalaya or El Pico. Its two most important buildings are the Gothic parish church, which dates from the 16th century and contains wonderful baroque carvings; and the chapel of Humilladero, which is the oldest structure in town. The fishermen's taverns, which are located in a narrow cobbled square next to the sea, are the main tourist attraction.
