Explore cave

The formation of rock cave formed by erosion, erosion and collapse along the limestone level is the result of long-term dissolution of groundwater in the limestone area. The main component of limestone is calcium carbonate (CaCO3), with a chemical reaction in water and carbon dioxide to produce calcium bicarbonate [Ca(HCO3)2], which is soluble in water, so there are voids formed and gradually expanded. After the formation of the karst cave, if the ground rises, or the diving surface drops, the karst cave originally developed in the horizontal flow zone will rise to the seasonal change zone or even the vertical penetration zone, becoming a karst cave that dries dry or intermittently dried up for a long time. These caves are usually located in the upper part of the mountain and sometimes distributed in multiple layers, therefore, they are called high caves. A semi-developed cave without crowded visitors, hiking along the river, feeling the magic of nature, with low physical requirements for both men, women and children, it needs to wear a helmet during the expedition and fix their headlights to free your hands and better protect themselves. The former part is the dry hole, where the central part can play the mud bath, and finally inserted directly into the bottom of the underground river for foot, directly to the other side of the mountain. The cave with cool ventilation and clear water is a good place for summer. It is an perfect place for outdoor education and exploration to learn about karst landforms, limestone formation, and the characteristics and formation of karst caves and underground rivers. #nationalpark
