The entrance opens into a chamber packed with bronze cave sweepers, so dense you have to work your way through them, and from there you rise through the chimney towards the light.
Profile and sections
The entrance opens into a chamber packed with bronze cave sweepers, so dense you have to work your way through them, and from there you rise through the chimney towards the light. If your buoyancy is excellent you can also enter a very narrow tunnel that leads into a small cave, from which you swim straight back onto the reef. Visibility is usually 15–20 m.
Practical: one of Koh Haa's favourite dives, on the day trips from Ko Lanta.
- Depth and profile
- A grotto at ~16–18 m leads into a vertical chimney with two exits at 5 m (Phoenix Divers, Aussie Divers; IDC Phuket describes it the other way round, from 5 m to the bottom at ~18 m). The site itself goes to 35 m.
- Configuration
- Short swim-through with daylight at both ends: recreational gear with a torch (estimate).
