Adventurous holidaymakers can now book their trip to the world’s largest cave, named Son Doong, located in Phong Nha Ke Bang National Park, Vietnam.
Small groups of eight people will be able to make their way through the dark tunnels with an expert guide, and see beautiful geographical shapes and structures, including a 250 metre-high cliff, home to species including monkeys, hornbills and flying foxes.
Inside the awesome structure there’s also an 80-metre sheer drop, which is 200 metres wide and nine kilometres in length. This space alone, could house a small city.
Trips to this magnificent place do not come cheap. Local tour operator Oxalis Adventure Tours has priced them at the level of a once-in-a-lifetime experience, trekkers will pay £1,900 for the tour, but they say it's entirely worth it.
The first commercial exploration of the cave took place in August by a tour of cavers incuding people from the US, Norway, Russia and Australia.
Caver Luke Ford visited the cave for the first time last month:
"As we approached the first jungle in the cave where the roof had collapsed, we saw clouds rolling into the massive chamber, and it left us all absolutely speechless!" said Ford.
"Not only was the cave spectacular, but also the entire team who put on the trip for us – including our team of 14 porters – made sure we went home with memories that will last a lifetime."
