Settled at the end of Hang Son Doong, the Great Wall of Vietnam is a gigantic overhanging mass of flowstone that blocked the way deep inside the cave, above 60m high, and linking to the biggest chamber by a lake 500m long.
With an enormous measure and a deep location 6km from the first cave entrance, the Wall is rated as a “natural masterpiece” by cave specialists, though its image is never as widespread as the two Collapsed Dolines (Sinkholes), Garden of Eden and Watch out for Dinosaurs.
Climbing over this Wall is definitely not an easy challenge to adventurers, even to expert climbers. They compel to use professional gears and follow under conduct of speleologists.
Experiencing over the centuries, calcite crystals left behind water layered themselves around small sand particles, enlarging over time, and forming drip by drip rare cave “pearls”.

A skeleton of a mountain goat has fossilized for roughly several hundreds of years.
Behind the wall, there is a 600m passage leading to a second entrance into the cave.
