The dive

At the opening of this inland blue hole you see sulphur rings. On top lies fresh water with 3–9 m visibility from decaying plants; below the halocline visibility is suddenly >30 m.

A hydrogen sulphide (H₂S) layer sometimes sits at the halocline (~-27 m).
Deep: the guided group dive already went to ~-46 m and the cave is explored to ~-133 m: plan your gas and your turn depth for that.
Profile and sections

At the opening of this inland blue hole you see sulphur rings. On top lies fresh water with 3–9 m visibility from decaying plants; below the halocline visibility is suddenly >30 m. The water is 28 °C, and the walls carry a white bacterial coating. The dive is almost entirely in the overhead.

According to the tourism site it is the second-deepest cave in the Bahamas. It was explored by Cousteau's team (Wikipedia).

Depth and profile
Fresh water down to the halocline at ~-27 m · group dive ~-43 to -47 m · ~120 m of passage · explored to ~-133 m (Brian Kakuk: -108 m on air, later -132 m on trimix)
Configuration
In 2011 Small Hope Bay Lodge required cavern certification and fully redundant cave gear. Explored to ~-133 m: plan your gas for the depth you dive. Everything has to be carried ~800 m.
DPV: unknown
No data; ~800 m carry to the entrance

This is how the planner decides who in your team may dive this cave. Rules your own trip adds (organizer, a mail, the AI) show with your trip.

How to get there

~45 min on dirt roads from Small Hope Bay Lodge, then a ~800 m walk through mud and roots to the pond (2011). Guided by Small Hope Bay Lodge at the time; ask whether that is still possible.
