It is the largest cave in the world, with its own sheer rocky cliffs, jungle-like vegetation and climate.
So it is no wonder photographer Ryan Deboodt, 31, relied on a drone to capture footage showing the immense size of the Hang Son Doong cave in Vietnam.
The result is a spectacular video showcasing the dramatic topography inside the cave, which is 5.5 miles long, 650ft wide and 500ft tall.
