From the municipality of Loiu we take the BI-3704 road in the direction of Unbe Height. After one kilometre we come across an intersection to our left, heading for the University of Leioa on the BI-3731 road. We take this road and turn off again to the left a few metres on, to access immediately the Akarlanda recreational area.

  • Akarlanda is a recreational park that is fully integrated in nature, offering all kinds of modern conveniences that will render our stay there more comfortable. For many of the inhabitants of Bizkaia, if offers a splendid alternative to the over-saturated beaches of our coastline.
  • In the upper part of the recreational area is a circular space bathed by the sun and surrounded by beautiful mimosa hedges which are covered in yellow in the winter. In this magnificent corner are the toilet block, a large group of tables with benches, a children’s playground and the forest watchtower. The remaining facilities are spread around the vast surroundings, some in the sun, some taking advantage of the abundant and varied woodland.
  • The facilities at the recreational area are rounded off with a large car park and a very comprehensive range of sports facilities, amongst them a small football ground, basketball courts, skateboard areas, a sports training circuit...

Martiartu Tower


We return to the BI-3704 road in the direction of Unbe Height, and soon find a turnoff to the left, where a sign reads "Martiartu".

We travel along the valley on a narrow road that runs amongst many chalets and country houses, finally reaching the Martiartu Tower, next to the sports centre bearing the same name. Located on the boundaries with the municipality of Getxo, and to the south with the Unbe mountains, it takes up the upper part of a hill, accompanied by a cluster of oaks and a small hermitage.

This is probably one of the finest examples of towers around Bizkaia. The entire outside is kept in a perfect condition. It is one of the few towers that were not knocked down, and therefore retains its battlements intact. This construction is an uncommon case in our region, as it is entirely built of cut stones.

It has a beautiful gargoyle that represents the figure of a lion and a peculiar geminated gothic window that belonged to the lookout cupola. Many vassals and noblemen in former times crossed the main door, accessed from a steep staircase, on their way out to fight on the battlefields.

A lesson in geology


After a couple of kilometres along the BI-3731 road, we reach the University of Leioa. To the right of the university premises is a long strip of land dotted with groups of rocks.

These minerals, placed there by the Faculty of Geology, are some of the most representative in our region, and have attached to them small educational panels indicating the name, composition, geological age, and the place in Bizkaia where they were found.

We can learn to pick out, amongst other, rocks such as conglomerates, limestone, sandstone, marl, basalt, siderite, slate, ophite, gypsum...

The university features an exhibition room at the library and offers a variety of cultural activities, open to the public every working day of the year.


The Virgin of Unbe

We reach the Unbe Height and continue on the BI-3704 towards Urduliz. After kilometre point 15, we see to the right of the road a turnoff indicating “to the house of the virgin”. A narrow road climbing up the northern mountainside of mount Unbe brings us to the site.

Inside a small house is a chapel where the image of the miraculous virgin of Unbe is worshipped. Nearby is a fountain that gathers the water from a small stream. The water is not safe to drink, however a series of taps allow visitors to wash the faces and feet of the sick, as the custom goes.
