Bizkaiko bira

Bizkaiko bira is a 91.6 km National Hiking hiking trail covering an interesting stretch of countryside.

Covering 91.6 km, this is a true long-distance trail best approached as a multi-day journey through varied terrain.

This linear trail moves from one end to the other without looping back. A return journey by transport — or retracing the path — is needed to get back to the start. Follow the GR 123 waymarkers throughout to stay on the official trail line.

As a National Walking Network (NWN) trail, this route represents a nationally recognised hiking corridor. Infrastructure and waymarking are maintained at a high standard.
