Only here: The only way to camp at the edge of Kong Collapse without committing to the five day expedition.
Three connected caves and nearly seven kilometres underground, camping at the edge of the Kong Collapse sinkhole without doing the full expedition.
What you actually do
- Three caves in sequence: Tiger at 1.6 km, Hang Over at 3.2 km, then Hang Pygmy
- Nearly 7 kilometres of cave passage across the three
- Camp beside the Kong Collapse sinkhole, Vietnam's deepest
- The Dinosaur Spine, a cliff path along an exposed rock ridge
- A 10 metre rope descent
- Includes Hang Pygmy, so you see the fourth largest cave inside the longer trip
Is this the right tour for you?
Worth reading before you book. Age limits and group rules rule people out more often than fitness does.
Book it if
- You want the most cave passage of any tour short of the expeditions
- You want to see Kong Collapse without committing to five days and 35,000,000 VND
- You are a steady walker and comfortable underground
- You are 15 or older
Look elsewhere if
- You want to descend into Kong Collapse. This camps at it, it does not go down
- You have only two days. There is no shorter version of this route
- Exposed ridges bother you. The Dinosaur Spine is a genuine drop on both sides
Day by day, all 3 of them
Tiger Cave
Briefing and kit in Phong Nha, then into the forest to Tiger Cave, about 1.6 kilometres of passage. In the dry months the route includes a 300 metre swim; from September to November, when the water is high, the operator replaces that section with a trek. Camp is set in the forest.
Hang Over and the Dinosaur Spine
The long day. Hang Over runs about 3.2 kilometres and is the most decorated of the three, and the route out crosses the Dinosaur Spine, an exposed rock ridge with a path along its crest. Camp on this night sits beside the Kong Collapse sinkhole, so you can look into the drop that the five day expedition descends.
Hang Pygmy and out
The last cave is Hang Pygmy, reached with a 10 metre rope descent into the chamber, then the walk out through the forest to the road.

When to go
Runs year round, but the 300 metre cave swim on day one is replaced by a trek from September to November when water levels are high.
Questions worth asking first
Does this tour go down into Kong Collapse?
No, and it is worth being clear about that. You camp at the sinkhole and can see into it, but the 100 metre rope descent to the bottom belongs to the five day Kong Collapse Top Adventure. If descending is the point for you, this is not the tour.
What happens to the swim between September and November?
The operator swaps the 300 metre cave swim on day one for a trek when water levels are high. That is a seasonal safety call, and it is the one genuinely tour specific season note in the catalogue. Everything else runs as advertised.
Is it worth 4,600,000 VND more than the Hang Pygmy tour?
You get a day more, two extra caves and the Kong Collapse camp; Hang Pygmy on its own is the two day version of the finale. If your schedule allows three days, this is the better trip. If it does not, you are not missing Hang Pygmy by taking the shorter one.
What is the Dinosaur Spine?
A narrow rock ridge crossed on the way out of Hang Over, named for its serrated profile. There is a path along it and the safety team walks it with you, but it is exposed, so tell your guide in advance if heights are a problem for you.
