The Fórnea stream originates here, in the Cova da Velha cave, where a natural spring flows almost all year round. However, due to the limestone soil, the water easily infiltrates, traveling through underground galleries instead of flowing freely on the surface. As a result, the stunning Fórnea waterfall only reveals its full grandeur after days of heavy rain.

The Fórnea Waterfall is located right in the heart of the Serras de Aire e Candeeiros Natural Park, and is fed by the Fórnea Stream, which in turn flows from the Cova da Velha cave.

While this was my second visit, I've enjoyed it as much as the first one! The first gallery of this system of caves was discovered by locals in 1947. Of course people were curious and had to investigate further. What is known today is that the cave reaches 11 Kilometers in length which makes it the biggest and most important in Portugal. The formation of the cave goes back 150 million years to the middle Jurassic age when dinosaurs inhabited this region. They found traces of species who inhabited these caves, some of it on display. A part of the cave-system was opened to the public in 1974 with many improvements in safety for the visitors in later years. At one point colored lights found their way in with some spectacular and dramatic effects. My photos inside the cave are in the wrong order, not sure how to interchange them or what I've done wrong when uploading, sorry!

Nice quiet route. No water at the waterfall, unfortunately. Because that would give a different experience, certainly worth it for the beautiful views

Actually, there is supposed to be a waterfall here. Unfortunately dried out due to the drought in July.

The Fonte do Peão, built in 1884, is one of the symbols of the parish of Monsanto. It is covered in tiles that depict rural life. The water in the Fonte do Peão comes from a spring and flows regularly throughout the year. According to information obtained from local residents, the water is good for human consumption and is used as a source of water for the many travellers who pass through there.
