The waterfall is part of the drainage basin of the Ribeira de Colares, which eventually flows into the Atlantic Ocean near Praia das Maçãs.
The geological composition of the site consists of metamorphic rocks typical of the western Sintra range.
The waterfall is located in a transition zone between Mediterranean and Atlantic microclimates, fostering diverse moss and fern growth.
Fervença Waterfall is a secluded natural cascade located in the Terrugem parish within the Sintra municipality. The site features a series of rocky tiers where the water flows through a dense, wooded ravine. It is positioned along the Ribeira de Colares, which serves as a natural drainage for the surrounding landscape. The area is characterized by its uneven, unpaved terrain and dense vegetation cover. Visitors primarily access the waterfall via narrow, unofficial dirt trails. As of mid-2026, the site remains an undeveloped natural spot without formal visitor infrastructure or signage. The water volume fluctuates significantly based on recent rainfall patterns in the Sintra hills.
