Go to Hasparren, then take the D152 to the Zelhaia district. After the pelota court, continue straight on towards Mendionde on the D152. Park at altitude 274 in a bend (picnic area). There are a few spaces available on the right and left of the road.
(S/E) Turn right, north-west, onto the dirt track that climbs uphill and is marked in yellow (sign). It joins the Route Napoléon at altitude 299. Just after a wide bend, you will come to a multi-junction and take the path furthest to the right. Pass to the left of the Betirigaztenea farm. Immediately after, in a bend, look for a path that branches off to the left.
(1) Leave the Route Napoléon and take this path on the left, heading west. Cross several easy fords. The path becomes grassy. Join a track coming from the right. Pass to the right of a very pretty barn and head south. Cross a copse of trees. Cross more fords and, after a bend, head north-west towards a fork.
Leave the main path on your right and take the path on the left that goes uphill. Follow it to reach a small pass; a very pretty spot with a beautiful view.
(2) Leave the path that dips to the right, reach a large enclosure and follow it along the left, heading due west. This path joins the main path that climbs directly to the summit of Ursuya.
(3) Take this path downhill, west then north, and you will reach a pretty hut. Go around it and head south. At the next 90° bend, take the path on the left. This path makes a wide circular loop west, south, then east. You will arrive at a hut.
(4) Leave the track and take a path to the left of the hut that climbs steeply through the grass. You will arrive at a small plateau with a cistern. The path descends to a concrete track. Normally, a grassy path allows you to follow a contour line and avoid descending and climbing back up the track.
The gate is not easy to open, so you have to squeeze through the barbed wire. For this hike, the route follows the track to a converted barn.
(5) Take the path that passes to the left of the barn and, at the next intersection, above Mokorreta, turn completely left and follow a path that climbs very steeply. Join a main path coming from the right and take it to the left, up to the upper meadows. Follow them along the ridge to the summit of Ursuya (Basque flag).
(6) Retrace your steps for about a hundred metres and descend eastwards on the main path until you reach a fork.
(7) Leave a grassy path that descends on your right and continue straight ahead to reach the Gaineko Ordokia ridge (590 m). Descend to a fork at an altitude of 540 m.
(8) Turn left. Pass the first crossroads, go straight ahead and continue to the second (altitude 486).
(9) Take the grassy path opposite for a few metres until you reach the next small plateau.
(10) Turn onto the grassy path on the left and then immediately take the one on the right heading north-east and descend until you come to a fence.
(11) Turn right, walk along the meadows and pass three barns in succession. Join a beautiful track and turn left. Pass to the right of a pumping station and continue to the car park (S/E).
