Oxalis is the only private company licensed to explore Son Doong. Quang Binh province’s authorities approved tours from now till 2030. Earlier, the licence was only given annually.
The province requires the tour operator to achieve economic efficiency and ensure tourist safety while promoting Son Doong, a fast-emerging tourist destination.
Due to limited space, registration for Son Doong tours must be made well in advance. According to Oxalis, 570 slots are available for 2020.
A four-day expedition costs 3,000 USD.
Quang Binh authorities recently increased the number of tourists allowed to visit the cave over a one-year period from 640 to 900.
