Arantzazu hidden path loop

Our final morning, and it dawned clear and fresh from our rooms overlooking the gorge and sanctuary of Arantzazu. I wanted one final outing, and this route seemed to offer a chance to explore the bottom of the gorge that I'd been looking down on from the balcony. I ran it, from outside the hotel to the path along the streambed of the Urkullu Erreka. The path then curves round the shoulder of Arriona, a small peak, to head north-west below Aitzabal to eventually gain the gorge (Arantzazu Erreka). A very steep climb on zigzags up limestone shelves, almost 1000ft of climbing, gives a tough sting in the tail. Just over 44 minutes for the 7.5k route, much of that taken up by the final climb! Then it was down to Bilbao for pintxos, then the flight home.
