Journey Through the Largest Cave in the World
Son Doong Cave—the largest in the world—wasn’t discovered until 2009. Now, National Geographic grantee and photojournalist Martin Edström, takes us deep inside Son Doong as he tries to capture its overwhelming size and beauty in 360 degrees.
The effort to share Son Doong (also known as Hang Son Doong) with the world has been decades in the making. “There was a local farmer who found what he thought was an entrance to a cave in the ‘90s, but it was this big, black hole in the ground where no one dared to go,” Edström says of the cave, which is obscured by a dense Vietnamese jungle.
