The Son Doong Cave in Vietnam boasts the largest cave passage in the world. This huge and intricate cave system was created by water that had percolated down from a rainforest above, carving into the rock. Inside the cave sits a flourishing jungle, which grows 200 meters below ground level in an area where the cave roof has collapsed.
