The Artiga Baixa torrent is popularly known as the Ferrada de les Dames, and is, together with Ferrada Teresina, the most popular via ferrata of the entire mountain of Montserrat. It is a fairly technical ferrate, but also has overhanging sections where you will need to pluck up courage to be able to overcome them.
You have to be relatively fit in order to climb the vertical sections, and you will be constantly on the move for half a day.
