Is Son Doong fully booked?
Yes. As of 2026, both 2026 and 2027 are sold out. Spots for 2028 are open but fill fast, often within hours of release. Cancellations do come up, which is what the alert list is for.
How do I get a Son Doong cancellation spot?
Join a waitlist and watch for releases. When someone cancels, the spot is offered quickly, so the people who hear first get it. That's exactly what our alert list does.
What can I do instead of Son Doong?
Hang Pygmy is the world's fourth largest cave, you sleep inside it, and you can usually book it this season for a fraction of the price. Hang En is the gentler overnight with the famous sunrise swifts.
Can't wait until 2028? See Hang Pygmy, the giant cave you can book this season, or read the full Son Doong guide.
