Algar da Cerejeira is a remarkable geological karst formation, that is, a natural cavity or vertical sinkhole. These algars are typically formed in limestone regions due to the erosive action of water, which dissolves the rock and creates underground pits or caves. Algar da Cerejeira is therefore an example of this process, offering a fascinating glimpse into the depths of the earth.

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!
