It is reached by the road leading to the Artxueta repeater: at a very sharp left-hand bend, on the right-hand side there is an old concrete tank, from which a track leads off and is followed for about 800 metres until, on the right-hand side of this track and at the start of the forest in a Northerly direction, the entrance is found. The cavity is located to the N-W of Artxueta, at about 600 metres.
