Son Doong Cave Is So Big, It Has Its Own Rainforest
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.
