We leave the Information Center in the direction of the Xiprers school and follow the path on the left that climbs through the pine forest, until the next crossroads, where the direction of the Budellera itineraries is indicated on the right where we are heading After about 45 minutes from the start, we continue along the track that leads to the Budellera above. The path passes above Can Mandó, and a few meters further on it leaves Can Xoliu on the left. After about 25 minutes we find, on the right, the path that goes down to the source.
The site was landscaped by J.C.N. Forester at the beginning of the 20th century. There you will find a spring with mains water. From the Budellera you can also reach the Collserola tower. From the back of the small squares that make up the site, the path that descends towards Vil·la Joana leaves, but which we will leave on the right, a little further on, to follow a few meters to ca n'Estisora.
Going down the stairs, we will be able to see the beams and the pond of the farmhouse on the right and, following the track, in less than 15 minutes we will be at the bend of Les Monges, all the way down a stepped path to the right. On the other side of the road, go down the wooden stairs and continue along the path that follows the stream until you reach the leisure area of Santa Maria de Vallvidrera.
