We leave Colldejou following the GR-7 towards Llaberia. At 425 metres we reach a crossroads that we take to the right along a wide path; we continue upwards, leaving the GR. 500 metres further on we find a fork. We leave the track that descends and take the one going up to the right along the wide path. 525 metres further on, after a sharp bend to the right, we must take a faintly marked path on the left that runs through the middle of the forest. If we look carefully we will see some cairns at the entrance to the path. This path is not very easy to follow; we must head towards the mountain, climbing; there are some places where we will see orange-coloured marks, and higher up, when we come out of the vegetation, we will find some cairns. After covering 650 metres, when the scree slope begins, we turn left, traverse on flat ground and pass behind some rocks, where we will find the avenc del Niu de la Miloca. Very approximate coordinates.
