Why it matters
Why Hang Én Cave is worth your time
Hang Én is the third-largest cave in the world, after Sơn Đoòng and Deer Cave in Malaysia, with a passage about 1,645 m long, up to 100 m high and 170 m wide. It is known for three large entrances and a camping beach inside.
For those who cannot do Sơn Đoòng, it is the more approachable route into the biggest caves in the park, but it still takes fitness and preparation.

Plan your visit
How to experience it
Hang Én is visited on a guided two-day trip. You trek through jungle and across streams to the cave, camp inside the cave on a beach-like sandbar and return the next day. The operator provides guides, porters, tents and meals, and you carry your own small pack.
It is graded moderate by Oxalis, which does not mean easy: expect heat, humidity, wet feet and long hours on your feet. Basic swimming skills are not required, according to the operator's site, but check this when booking.
Book in the dry months and confirm that tours are running, because the wet season can close access. Pack light, wear quick-dry clothes and bring insect repellent.
Plan with confidence
Small decisions that make the visit easier.
- Book through a licensed operator
- Check the season and tour status before you travel

- Tell the operator about any medical conditions in advance
