Phong Nha Cave is famous for its rock formations which have been given names such as the “Lion”, the “Fairy Caves”, the “Royal Court”, and the “Buddha”. This cave is 7729 m long, and contains 14 grottos, with a 13,969 m-long underground river. The scientists have surveyed 44.5 km of grottos in this cave so far, but tourists can only penetrate to a distance of 1500 m.
Like most of the caves in this area, Phong Nha Cave has been continuously shaped by the Chay River. As one gets farther into the cave, the more illusory the stalactites and stalagmites look as they glitter when bright light is shone on them. The Son River flows into the mouth of the cave and keeps flowing underground, where it is referred to as the Nam Aki River, then this river emerges at a site 20 km to the south near Pu Pha Dam Mountain. The main Phong Nha cave includes 14 chambers, connected by an underwater river that runs for 1.5 km. Secondary corridors branch off in all directions. The Outer Cave and some of the Inner Caves have roofs between 25 and 40 meters above the water level. From the 14th chamber, there may be other corridors leading to similarly large chambers, but this area proves more dangerous for explorers because of the ongoing erosion of the limestone of the cavern. The Shallow Cave is located 800 meters from the cave mouth, where there is a spectacular landscape of sand and rock. Stalactites and stalagmites jut out like strange trees, exciting visitors’ imaginations.
Paradise Cave dubbed as “underground palace” Heaven is one of the wonders of the magnificent and magical world most. Cave is nestled deep in the World Natural Heritage National Park Phong Nha Ke Bang, and Surrounded by forested karst peaks, this remarkable cave system extends for 31,4 km, though most people only visit the first kilometer. The scale is breathtaking, as wooden staircases descend into a cathedral-like space with colossal stalagmites and glimmering stalactites.
It owns a length of more than 31.4 km; the width ranging from 30m to 100m, up to 150m at its widest point; the high from the bottom up to the ceiling at about 60-80m. British Royal Cave Research Association appreciates Paradise Cave as the longest Dry Cave in Asia, one of the most spectacular caves the association surveyed over the world. Paradise Cave owns a breathtaking, magnificent and magical structure that discoverers easily think about as a heaven palace on earth. In particular, the system of stalagmites and stalactites here retains a shimmering, fanciful beauty beyond the imagination of humans.
