Cycling Friendly route from Portugalete, heading towards one of the emblematic spots of the north, such as San Juan de Gaztelugatxe, to its belvedere.
On the way back, the Jata pass and the ascent to the belvedere are the biggest challenges for the cyclist, while on the way back the passage by Unbe will be the one that will allow us to add more meters of positive slopes on this cycling day.
