Hi, I'm Dat - Adventure Consultant from Oxalis team. The best time to do Son Doong Expedition is on mid-April, the weather is not too hot, not too cold, dry season in Phong Nha as well. All spots in 2022 are booked out. However, the departures in 2023 are open, please feel free to reach out to me via Whatsapp: +84372003642 if you have any questions. Regards, Dat Bui

Oxalis Adventure is the only operator running tour to Son Doong cave, its 4 days and 3 nights camping in caves plus a night before and after the tour. Its cost 3000usd per person. Tour only runs from Jan thru Aug every year. Please google Son Doong cave tour with Oxalis Adventure to book your trip. Cheers

The trip is something you have to plan a little in advance as you need to bring the right clothing etc. Also it becomes booked out months in advance so don't expect to just turn up and go. Liaise the Oxalis travel before you arrive. They respond quickly and provide excellent advice.

The tour is 4 days and about $3,000 Usd per person. You can book tour at Oxalis.

If your trainers are similar to trail-running shoes or sneakers with a good grip, then I’d say that is fine. I did the trail with rubber shoes that were like $2 and it worked like a charm. Just bring shoes that you can hike in on sharp rocks/muddy trails without slipping.

Yes. Swimming on the son Doong Expedition is optional.

You may have got the answer to this already, but Oxalis take very good care of everything, including your bathroom breaks. At the campsites, tented toilets are set up. They are western style toilet seats over a box with a bucket at the bottom. After you do your business, you take a scoop up a large amount of rice husk from another barrel and cover your 'business' with it. This is a composting operation which works very well and doesn't cause any bad smells. The porters take care of the buckets when they are full and dispose of the contents at a designated composting site. I hope this helps.
