Vietnam is a popular destination amongst cave explorers or “spelunkers” as they are referred to looking for a unique adventure amidst stunning underground landscapes. The country is also home to massive caves including Hang Son Doong which is one of the world’s largest. This cave structure is large enough to fit in a 747 plane and its ceiling is close to 800 feet tall! Areas such as Son La, Lang Son and Ha Giang are also known for their many fascinating caves. Those heading to the region and in search of a Vietnam hotel that is right on the beach can stay at Anantara Mui Ne Resort & Spa. This luxurious resort in Mui Ne also has its own spa where you can truly unwind after your many adventures.
