To reach the start, cross the border at Béhobie and take the N-121A towards Pamplona (Iruña in Basque). After 12 km, exit at Lesaka and turn right onto the NA-4000 towards Lesaka and Oiartzun. Pass through Lesaka and continue on the NA-4000 for 7.5 km. At a hairpin bend to the left between km 13 and km 14, take the small road branching off to the right towards the starting point, which is situated in the woods on the edge of the paths leading off on either side of this small tarmac road.
(S/E) Head west along thePR®-NA-17 Lesaka Agiña trail (PR® stands for Pequeño Recorrido, meaning ‘short walk’, and NA for Navarra, the province of Navarre).
(1) Ignore the turn-off to the right onto thePR®-NA-11 and continue alongthe PR®-NA-17.
(2) Turn right, begin the ascent by following the ridge line that runs alongside the woodland and reach the summit of Agiña (618 m).
(3) Continue westwards and descend along the ridge, first through a meadow and then through the wooded area.
(4) Follow the contour line to the right, then head due north to descend towards the lake via a series of steep hairpin bends.
When you reach the road, take the first right at the end of the bend towards the Ola Berri restaurant.
(5) Take thePR®-NA-11 path, marked in red and white, which branches off to the right at the bend. The path joins theGR®11, which is tarmac-surfaced.
