AB-2

On the NA 140, at the exit of the village of Abaurrea Alta, in the direction of Ochagavía, take the track on the left, called Erdiko Bidea, and follow it until it joins Medibarrengo Bidea without changing direction. Take the first fork to the right, which leads to the Ipetea area. Continue for about 100 metres and, to the right of the path, in a meadow, is the cavity.
