Hang Tiger, or Hang Ho in Vietnamese, was originally explored via Hang Dai Cao involving a long walk in and a traverse of a Hang Duat and Pitch Cave. From Pitch Cave, a jungle bash leads to a stream bed which is extremely slippy before leading to the impressive entrance of Hang Tiger. To see this cave, you will need to join the 3 days, 2 nights Hang Over Expedition, which also visits Hang Pygmy and Hang Over.
The main downstream entrance to Hang Ho is spectacular. Huge trees grow at 45 degrees next to the entrance perhaps due to the very strong draught. A small stream flows through the cave and soon the main passage which is around 25m wide and 40m high gives way to a lake and swimming is required. A shingle bank is reached and by staying on the right hand side of the passage an easier way on can be found. The passage then splits in 2 and the left hand branch climbs up a boulder slope to a choke. However the right hand passage continues climbing over a number of house sized blocks and both passages meet up again in a spectacular dry passage around 50m wide and 30m high aptly named ‘Monster Passage’. From here the exit of Hang Ho can be clearly seen 300m away. On the left a steep climb up gours leads to a complex of passages and a steep climb down on mud banks and boulders into more water filled passage. Here the dimensions are again huge and it is difficult to work out the walls or roof due to the dark nature of the passage. Down to the water you can go either left or right. To the left is a 200m swim to a beautiful enclosed doline surrounded by sheer cliffs a truly awesome sight. However no obvious way on is seen. To the right a swim leads through a low section to the entrance described in the walk in. This emerges in an entrance around 10m high and 15m wide in a dry river bed (In dry season) which if followed upstream leads to Hang About.
