The Hang En cave with 130 meters high and 150 meters wide is situated close-by to the Hang Son Doong, the largest cave in the world, which was recently discovered in 2009 by British cavers, led by Howard Limbert.
Photographer Lars Krux, 48, ventured into the cave with his wife Justyna Krux, and a party of tourists, in order to capture some stunning shots.
