From motorway A-8 take the ZARAUTZ exit.
If coming from San Sebastian there is a previous exit in Orio but it is better to take the next, the Zarautz one.
If you come from Bilbao, be careful when near Zarautz as only the two right lanes allow you to take the Zarautz exit (the other lanes heading to San Sebastian).
Once you have left the A-8 in Zarautz, and after the toll boot, go right ahead at the first roundabout and at the second roundabout take the first exit towards AIA-ORIO N-634.
When at the top of the Orio hill (Olaeta), turn right and take the AIA road GI-2631.
After about 2 km take the first road on the left to MANTEROLA. GI-4164.
Down this road for about 600 meters you will face a concrete paved track with a no entry traffic sign. Take it anyway and after 200 meters you will be at IbarrolaBekoa. .
