Avenc del Camanegra

On the N slope of turó d'Aguilar. To reach it, one must go up along a path that starts beside a torrent very dense with vegetation located right next to the masia de les Arenes, just when we come upon the first houses. The path is hard to follow, but one can still reach a col from where an abandoned track starts down the shady slope of the ridge that leads to turó d'Aguilar. After following it for about 200 metres we will find the pit on the right of the path. Very approximate coordinates.
