From the border at Irun, take the N 121 A road towards Pamplona. After about 15 minutes, take the Lesaka exit and head to the car park where the walk starts.
(S) From the car park, walk past the care home and cross the road, then continue following the GPS track until you reach the village boundary.
(1) On leaving the village, continue for about 3 km along the concrete track.
(2) At this junction, which marks the end of the concrete track, continue straight up the dirt track.
(3) Summit 1: Bidango Gaña, menhirs and cromlech. Retrace your steps for about 300 metres and take the path down to the right (south)
(4) Peak 2 – Almendruitz. This peak can be bypassed by taking the path along its western flank.
(5) Peak 3 – Pagolleta Gaña, menhir/cromlech. This peak can be bypassed by taking the track along its northern flank.
(6) Isaszelaleta Spring. A lovely spring with fresh, drinkable water.
(7) Unanu summit, featuring a cromlech. Stunning panoramic views. For the descent, retrace your steps for about 250m and take the small N-N/E ridge, which is not very pronounced at the start, marked by a yellow trail marker on a stone on the ground. A slightly steep path leads down to a junction with the track; continue along the path. There is a Yellow Circle marker on a tree at the start of the path. This summit can be bypassed by taking the path along its northern flank.
(8) Sastrene Pass and Fountain. On the right, behind an enclosure protecting a large table and benches, there is a wooden post with a tap attached to it. Continue the descent with your GPS to hand so as not to get lost amongst the many tracks you will encounter.
(E) Return to the car park after passing through the most picturesque part of this magnificent village.
