The Font d'en Mamet de Vilassar de Dalt is located in the Parc de la Serralada Litoral, which is located in the Molí d'en Cuquet stream, a few meters above the entrance to Can Mamet, at the foot of the track forest that leads from Can Maimó to Creu d'en Boquet.
It is a very rustic fountain: only the spout embedded in the rock, some wooden railings and four steps dug into the ground to go down to the natural pond where the water is collected. Due to the fact of being in the bed of the torrent d'en Cuquet (which maintains a good level of humidity and more or less flow throughout the year) the source flows almost always. Unfortunately, the water is not drinkable. Recently it has been fixed: they have cleared it, repaired the steps that go down and replaced the spout. The water flows through a tube embedded in the stones of the bank, a foot high, and falls to the ground forming a small pool that drains directly into the stream. To the right of the fountain, at right angles to it, there is a terrace attached to the margin. Above the fountain we find a sign with the name of the fountain and a series of warnings.
