To reach it we will set out on foot from the rest area located above Km.3 of the BP-1103 road from Marganell. We will go up the path that starts in front of the rest area and climbs until meeting the Can Maçana path (GR-172) at a distance of about 500m. We will take the GR in the direction of Can Maçana for another 550m; at this point, having already passed the turnoff to Coll de Port, we will leave the GR to climb up the bed of a right-hand stream to the base of the Gallaret, Ignasi Capeta and Foradada needles; the slot is found in the fissure between the Ignasi Capeta and la Foradada needles.
