Located in Quang Binh province, the longest cave in the world, ranks third to the Inca trail to Machu Picchu in Peru and the Burning Man festival in Nevada, the USA. As the world’s deepest cave, visiting Son Doong is a real challenging but attractive experience for adventurers.

To discover the cave, tourists must book their tours in advance. At present, there are less than 300 tickets available this year.

Those who are not lucky to get a ticket to explore the cave this year are advised to book now or register for the waiting list in 2020.
