The story I've been hearing is that access to Son Doong cave is for scientists/researchers only. No tourists are allowed access. Some tour operators are said to offer you a tour of Son Doong and than they take you to a different cave in a classic bait-and-switch.
AFAIK Son Doong cave requires the proper gear and skills to enter safely.
