The Son Doong Cave in Vietnam might just be the world’s largest cave. Nicknamed The Infinite Cave, the biggest chamber of Son Doong is more than five kilometers long, 200 meters high, and 150 meters wide. These photographs only capture just a small part of this enormous cave, which features a fast-flowing river and even its own forest. So next time you’re in the mood for some spelunking, check this place out.
