Take junction 9 (Ondarreta) of the motorway onto Avenida de Tolosa and then turn onto Calle Bernardo Estornés Lasa This turnoff is at the roundabout by the Diario Vasco building. When you’re on Calle Bernardo Estornés Lasa, keep straight on, go over the next roundabout and all the way to the end, where you then turn left (you’ll see a car showroom on the corner). Keep going straight on (with the showroom on your right). At the stop sign at the end of this road, keep going straight ahead (for about 1 km) and look out for the entrance to a small forest on your left. Turn off there, and after a further 1.8 kilometres you’ll see the campsite. There are signs to ‘Camping Igara San Sebastián’ along the road.
