Also known as Cascata da Bajouca, this waterfall is located in the town of Fervença, hence its name for which it is best known....
Rua da Bajouca 2705-915 Terrugem
Sintra
It is fed by a stream of reasonable flow, which comes from the Granja do Marquês and precipitates down the slope towards Ribeira de Cabrela, a tributary of the Lizandro River. In the past this stream drained the swamps that existed at Quinta da Granja or Marquês, as it was also called because it was owned by the first Marquês de Pombal.
This waterfall has a dazzling beauty, being in a corner that is a little difficult to access and perhaps that is why it is so charming, since it remains in its natural state.
