Son Doong Cave, Dong Hoi
(4.7/5 based on 70+ reviews on the web)
Marvel at underground vegetation and impressive stalagmite towers at Son Doong Cave, a huge cave system featuring its own jungle and a river. Over 8.8 km (5.5 mi) long, the cave was touted as the biggest in the world. Camp on the rough sandy beach on the banks of an underground river and admire the shades of light coming from large holes above the ground. Set in Phong Nha Ke Bang National Park, the cave was discovered by a local in 1991, but was not seriously explored until 2009. Explore ancient limestone walls created 250 m years ago and abseil into a true underground paradise with fabulous rock shapes fringed with vegetation.
