On the TV-7044 road going from La Riba to the Pinetell, at the height of the Molí de la Font Gran and just below the Campament Juvenil, we find a prepared parking place. On the right side of the road there is a path that goes down to the Brugent river, at this point almost always dry; we must cross it and follow the path towards the cliff. Soon we will find a crossroads: the right one goes to la Riba and to the cova Cartanyà, while the left one, which is the one we must follow, heads to the climbing routes of the Cingle dels Pins Alts and to the Penya Roja. Immediately we will find a new crossroads: the left one leads to the climbing routes of the Cingle dels Pins Alts, so we will continue to the right in the direction of the Penya Roja. Once we have arrived there, we find a small flat area where on the left of the path the mouth of the avenc dels Tres Grans opens; we will follow the path about thirty metres more and we will turn off to the right of the path about 15 metres, through an old cultivation terrace full of vegetation that will take us to the cave.
