Although the tour is quite short, it thrilled us. On warm days (it was 32 degrees for us) the tour was sweaty. Currently, the authorities have closed the path, a short section of 15 meters has slipped. However, the spot can be easily and safely bypassed.

The Lis River, whose source is in the town of Fontes, Cortes, is one of the few rivers in the country whose current flows from south to north and, in the final kilometres, from east to west. In winter and early spring, it is possible to see water emerging from the ground in surprising quantities. In the summer months, the source is usually dry.

The Sheep's Sink is an imposing natural cavity, named after the sink carved under a stalactite that, in the rainy months, pours out abundant water. In the past, this natural refuge served as a drinking trough for cattle.

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!

While the spring itself is dry in summer it must be spectacular when the rains are back in November. But the Rio Lis is also fed by water coming from inside the mountain and ground-water from the area, so water starts flowing a few hundred meters further down the riverbed, nice and fresh. There is a lovely path following it, and those who did some walking on a lovely summers day will really enjoy a little dip, maybe some swimming, but at least a bit of wading through it. There is easy access in several places, have fun 😀!
