As its name says in Basque, the sand on this 120-meter beach is fine and dark. Although it is very close to Deba, on the left bank of the mouth of the estuary, it really belongs to Mutriku. In the area there is a bar and parking.

From this viewpoint you can have very good views of the coastline and you can see the tip of Alkolea perfectly.

In this section made for pedestrians at the tip of Alkolea you will have splendid views over Alkolea beach, frequented by surfers due to its wave known as Punta Pitxarri. It is also a good point to observe the coast and its orography, especially on this side, since the other, although you can see Mutriku, is somewhat more covered by trees.

As you can see, this hamlet is located inside a sinkhole, which also makes it somewhat sheltered from the wind. This is another of the curiosities that can be seen in this area of great geological interest.

In the old village of Ziñoa there was everything and they were self-sufficient in themselves. They had agriculture, livestock, a winery, a mill, a carpentry, a bread oven and even a lime kiln.

This is a good point from which to observe the central depression of Olatz, 250 meters high. This depression has been formed over thousands of years by the action of water on the limestone rock. As part of the Olatz georoute, you can find an information panel here.

With 616 meters of altitude, you can find a geodesic vertex on this modest peak surrounded by vegetation known as Banderako dotta or Arno, the name that can be seen on the plaque and which also gives its name to the limestone massif in which it is located. Its other name, Bandera (Banderako puntea) refers to the fact that in the past this place was already used to send messages to ships on the high seas.
