Meet the site
The New Blue Hole is listed by the Marine Life Network as a recently discovered feature in the Pompey Complex, about 100 m in diameter, with sheer walls reported to go down as far as 90 m. It is recommended for experienced divers only, in contrast to the shallower Cockatoo Reef blue hole nearby. Little else is published about the site. The sheer walls and great depth suggest a dramatic dive into deep blue water from a shallow rim, with the upper walls likely covered in coral and the deeper sections dim and sparsely populated. The depth range listed for recreational diving is 1-40 m. Because it is remote, tidal and deep, it should be approached as an expedition dive: recreational divers should stay within 30 m and remain on the wall, while any deeper exploration requires full technical training, equipment and support. Research on the Pompey blue holes identifies holes at Cockatoo and Molar reefs; whether the 'New Blue Hole' corresponds to one of these or is a separate feature is not clear from available sources.
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.
The New Blue Hole (Pompey Complex) is recorded as Sinkhole/Cenote in Swain Reefs. The listed access is boat (multi-day/liveaboard). Confirm the actual meeting point, route and permission to visit; a map pin does not establish any of these.
Topics flagged by the stored research
These are questions prompted by the existing notes, not a verified or complete hazard assessment.
- Current and timing
- Ask how the operator assesses the current window for the actual route. Historical tide notes are not a departure instruction.
- Lines and obstructions
- Discuss any known entanglement concerns and the suitability of the planned area.
- Planned depth
- Confirm the intended route and training requirements; the recorded maximum is not a target.
Historical access notes exist for this record, but have not been independently verified for current use. Request current directions from the operator or site manager rather than following an old entry description.
Questions, answered
Is The New Blue Hole (Pompey Complex) suitable for my certification?
The record lists Technical (decompression). That does not establish suitability for every route or day. Share your training, recent experience and equipment needs with the operator and ask about the specific proposed dive.
Can I book The New Blue Hole (Pompey Complex) through YouDive?
YouDive is an independent research directory. Contact an operator directly to confirm whether it currently runs the trip, the inclusions and the booking terms.
