Vietnam caves are impresive to say the least and this country is home to the largest cave passage in the world known as the Son Doong cave. In 2009 the cave was explored by a Britih team who found a chamber inside which is over five kilometers in length, 200 meters high and 150 meters wide.
This cave is known to be at least 2.8 miles long, the exact length is not known though as the experdition was cut short due to flood waters.
As far as visiting the cave goes tour guides can be booked to lead groups to the entrance, but the cave is thought to be quite dangerous as theres a very large river running inside it. Any kind of deep exploration can only be done as part of a specialist team, which is a shame as the cave holds some impressive sights, such as giant stalagmites which stand at over 230 feet (70m)high.
There are 7 main Vietnam caves, which are listed below:
Lang Trang
Marble Mountains
Phong Nha cave
Phong Nha-Ke Bang National Park
Son Doong Ca
Tam Cốc-Bích Động
Tham Khuyen
If your looking to visit some caves while in the country, the most highly recommended is the marble mountains. They are a cluster of five marble and limestone hills located in Ngu Hanh Son ward, south of
Da Nang.
All of the mountains have cave entrances and numerous tunnels, and it is possible to climb to the summit of one of the peaks. Several buddhist sanctuaries can also be found within the mountains, making this a famous tourist destination. Excursions can be booked from many places in
Da Nang.
Another stunning series of caves can be found in
Halong bay, but most of these caves can only be visited by boat and arn't quite as big the 7 listed above, but are still an amazing sight.
