|One of the most interesting natural sights of Bér village and Nógrád county is Nagy Hill, which is built of volcanic andesite columns. This special geological value was created following a volcanic eruption 8-10 million years ago. At the top of the hill we find the area called andesite slide, which is formed by a slide-shaped wall of 5-6 angle andesite blocks 8-10 meters long, 30-40 cm in diameter. Such bent andesite columns are also a rarity worldwide, as we know of only four such places in the world besides Bér - the most famous is the Devils Tower in the United States. Not far from the slides lies a sea of andesite stone, the stones of which detached from the larger rocks under the influence of natural forces and stopped in the tree-free area of the mountain. In 2014, at the foot of the andesite rock spill, next to the geological study trail, a stone exhibition was made, featuring 12 rocks from the area. With the help of the information boards placed here we can learn about the geological history of the area.|
The 402-meter-high Nagy Hill has been declared a nature reserve and is now part of the Bükk National Park. The mountain is interesting not only for its famous andesite columns and stone sea: its flora and fauna are also significant.
