Son Doong Cave, Dong Hoi

4.7
#5 of 12 in Things to do in Dong Hoi
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.

    So let me get this straight, in Pattaya, Thailand I paid $15 to see a temple that's been hand carved by humans for over 30 years and doesn't have a nail in it. Yet you found a cave and because you have a monopoly deal with the government you can charge $4000,or $1000 per day for me to see it? Absolutely retarded pricing for a BRITISH company that is not investing any of this money back into Vietnam. All of you people stupid enough to pay this price are only serving to enrich a few priveleged people while keeping the country poor. I've been on a 3 month vacation around Europe and Asia and have only spent twice that amount. Stop supporting this terrible company and promote the competition trying to get government approval so that the prices will become reasonable for everyone.
