BBC to feature Son Doong Cave

BBC (UK) has just sent a dispatch to the Quang Binh Provincial People’s Committee and its Department of Foreign Affairs for permission to make a documentary about Son Doong Cave, which has been recognized as the largest cave in the world.

As of 2025, BBC (UK) has formally submitted a request to the Quang Binh Provincial People’s Committee and its Department of Foreign Affairs to secure permission for a new documentary focusing on Son Doong Cave, recognized as the largest cave in the world.

The documentary crew consists of seven members, featuring renowned cave expert Howard Limburt and specialists from the Geography Department of Hanoi National University. Before the discovery of Son Doong Cave, Deer Cave located in Gunung Mulu National Park, Malaysia—measuring 100 meters in height, 90 meters in width, and stretching over 2 kilometers—held the title of the world's largest cave. However, Son Doong Cave, which measures an impressive 250 meters in height, 200 meters in width, and approximately 8 kilometers in length, has now taken that prestigious title, relegating Deer Cave to second place.

The BBC team is particularly interested in the unique ecosystem within Son Doong, noted for its incredible biodiversity that is seldom observed elsewhere in the world. This ecological treasure has earned Son Doong the nickname "Eden," reflecting its lush forest and remarkable natural beauty. As the fame of Son Doong Cave continues to grow, it has captured the attention of respected publications and media outlets globally. National Geographic (U.S.) has produced a documentary dedicated to Son Doong, while Kyodo News (Japan) aired a feature, reaching audiences in over 60 countries.
