Neptune House is a stretch of the Anda wall with a cave in it. The opening sits at around 29 m, and behind it a narrow corridor runs some 20 m back to a room at 26 m. The wall outside is thick with sea fans, and the cave interior is where the macro on this site is.

The dive
The dive is a wall dive first. The face is colourful and thick with sea fans, and worked at an ordinary wall depth it makes a full dive on its own without going near the cave at all. The cave entrance sits low on the face, with its opening at around 29 m, so the deep part of the profile comes early rather than late.
Inside, a narrow corridor runs about 20 m back from that opening before it widens into a room at 26 m. It is single file and unlit, and the macro life in there is the payoff — the reason to carry a torch rather than just look in through the entrance. Coming out, the wall is there to ascend along, which keeps the shallow end of the dive over the sea fans.

Season follows Anda: Nov–Jun is the main season; the south-west monsoon and typhoons make Jul–Oct unreliable on this exposed coast.
Know before you go
- The cave is a genuine overhead: a 20 m corridor from an opening at around 29 m to a room at 26 m, single file and dark, so it needs a torch, a light-failure plan and gas held back for the way out.
Questions divers ask
How deep is the cave at Neptune House?+
The opening is at around 29 m on the wall, and the corridor behind it runs about 20 m back to a room at 26 m. The wall itself can be dived shallower if you would rather stay out of the overhead.
