Gorbeia and Urkiola Natural Parks

Gorbeia and Urkiola are two names that any nature and mountain lover should not forget to include in their agenda when visiting Bilbao Bizkaia.

The Gorbeia Natural Park, presided by the emblematic summit of the same name (the highest in Bilbao Bizkaia, at 1,482 m), offers the opportunity of going on numerous hikes and mountain routes in an environment of unique natural, faunal and geological wealth.

Meanwhile, the Urkiola Nature Reserve is home to the beautiful sanctuary of Urkiola and another of the area's most famous peaks, the Anboto. It is also an ideal area for bird and animal watching.

In the Urkiola landscape we can also admire truly striking geological structures, such as the Ojo de Atxular, which offers spectacular panoramic views of the surrounding valleys, and the crests of the Itxina Massif.

A Journey into the Depths of the Earth

In Arratia - Nervión you can travel from the highest to the deepest: we are referring to the impressive Baltzola Cave, located in the municipality of Dima.

The interior of the cave is home to striking rock formations and is well worth a visit, but its signficance goes beyond the geological interest: the archaeological remains that have been found in this cave system bear witness to the presence of humans in this area since time immemorial.

Near the Baltzola cave is also the Jentilzubi arch, a stone structure that shows what the passing of time, water and the vagaries of nature can create.

Otzarreta Beech Forest: the Enchanted Forest of Bilbao Bizkaia

With its beech trees with twisted trunks, the streams that run through it and the thick blanket of reddish leaves that covers it in autumn, the Otzarreta beech forest is probably one of the most photographed spots in Bilbao Bizkaia.

This forest, which looks like something out of a fairy tale, becomes a place of peace, reflection and connection with nature. The whisper of the wind through the beech trees and the murmur of the streams as its only companions make it a truly unique experience.

The Source of the River Nervion, Pure Strength and Beauty

The Nervion River, the same watercourse that kilometres downstream crosses the city of Bilbao, has its source in the Arratia - Nervión region. It is a true show, with a mighty 222-metre waterfall¬—the highest in the whole of the Iberian Peninsula.

From the nearby viewpoint one enjoy not only the waterfall itself and the deep canyon into which it flows, but also an incredible panoramic view of the surrounding area, an image full of mountain peaks, hills and dense forests.

As you can see, the Arratia - Nervión region has a lot to offer. These valleys are a real treat for your senses and an experience of genuine connection with nature that will make you forget your routine.

Exploring this environment is more of a privilege than a journey. One that is at your fingertips.
