Moment of Joy

The temperature in the cave is kept at around 11 degrees Celsius throughout the year, and the footholds are wooden and stable, making it safe to visit. The cave walls are lined with stalactites of various sizes and shapes, and if you look carefully, you can find fossils of corals and other animals that lived in the Cretaceous Period. Furthermore, some of the geological formations may resemble common objects, such as this rabbit-shaped boulder.
