@jamerold: Deep inside the heart of Phong Nha-Kẻ Bàng National Park lies Paradise Cave (Động Thiên Đường), a subterranean marvel often called the "Underground Palace." Stretching an incredible 31.4 kilometers, it is one of the longest dry caves in Asia. Discovered in 2005, its colossal chambers house breathtaking, naturally sculpted stalactites and stalagmites that have been forming over 400 million years. Walking along its wooden pathways offers an awe-inspiring glimpse into Earth's ancient geological history. #vinh #vietnam #fyp #cave #foryoupage
