Start: By car; cross the border at Dantxaria (Dantxarinea) and continue on the N-121-B then, after about 1.5km, turn right onto the NA-4402 which takes you to the center of Urdax. Park near the San Salvador monastery.
(S/E) Head East past the "Turismo", walk through the Nivelle and turn right.
(1) After a few minutes, turn right onto the path marked "Ruta de la Ferraria". This path overlooks the river. At the top, ignore the green/white signposted path which climbs to the left.
(2) 300m further on, you come to a house/shed, leave the track that climbs to the left and take the path that descends to the right of the house, alongside a fence and fruit trees.
(3) After about 4 minutes, leave the track and take a right-hand path down into the forest (it's a good way down!). At the bottom, cross the river on a footbridge and climb up to pass behind the Bake Ola farm. Take the track through a large gate.
(4) Reach a track on the right which leads down to the village. Join the village square near the fountain (S/E).
