The summit is 250 meters high and can be reached via a singletrack trail from the forest road. It's best to climb from the Bilbao side and then descend the singletrack towards Basauri. Coming from Basauri, it's not really rideable; pushing would be necessary.

I understood that this was Peñas Blancas or Apuko Txiki, and that Apuko is the next one, which is higher. I'm in a mess. What about this...??
