The starting point of the walk is at the car park, at the entrance to the village of Arantza (or Aranaz in Basque), on Rue Beheko. To get there, see the ‘Practical Information’ section.
The walk is signposted, either by signs or by blue and white markings. The suggested route is almost entirely a return walk, except for a short section where you can take an alternative route.
(S/E) From the car park, head towards the village along Rue Beheko. Walk past the school, where you’ll find the first signpost; follow the direction for “otras rutas” (other routes). You’ll then pass the town hall. The street bends left and then right. Carry on to the right, where you’ll come to a second sign (Putzubeltza 5.5 km), and take the next street leading down to the left (there’s a sign for Aterpe), Rue Osina. Continue along this street without turning right or left. You’ll reach a junction where two streets are separated by a low wall. Follow the left-hand street (towards Aterpe) and, immediately, take the small stony path on the left, at a third signpost. Look out for the white and blue markings and follow them.
(1) Turn right, following the markings.
(2) You’ll come to a concrete track. Turn left, then, shortly afterwards, turn right in front of house no. 13301. You’ll reach a junction with a sign indicating that your destination is 3.5 km away. Turn right and head down a concrete road.
(4) At a fairly large hole on the left-hand side of the road, leave the road and continue straight on along the dirt track, following the white and blue markings. In the middle of the forest, pass a lovely fountain. You’ll come to another sign indicating that your destination is 2.5 km away.
(5) Carry on straight ahead. 100 m further on, look out for a wooden sign by the side of the road marked ‘Putzu beltz’. Leave the main road and take the small path on the left. This leads onto a concrete track
(6) Follow it to the right.
(7) At the junction, take the path on the right. Shortly afterwards, at the crossroads, go straight on. You’ll arrive at the farm known as “Beraskun”.
(8) Turn left and head for the Putzubeltz waterfall.
(9) Return along the same path in the opposite direction.
(6) Suggested alternative route for the return journey, following this route: continue straight on along the track. Admire a few bordas and, in particular, note the very large house-shaped letterbox on one of them – a common sight in the region. About 800 metres further on, head down to the left for a few dozen metres to rejoin the path taken on the way out.
(3) Opposite, follow the outbound route in the opposite direction.
(2) On the zigzag section, don’t forget to take the small path on the right at the letterbox.
Continue on to return to the village of Arantza and then to the car park (S/E).
