Other people's footage, not advice: how someone else dives here says nothing about what suits your team. Dive within your training.

The dive

The entrance is a shallow pond (~1.3 m); right behind it lies a chamber ~12 m high with clear water (showcaves.com).

Part of Old Freetown system. Also in this system: Owl's Hole (Old Freetown system)

Cavern and cave: Calabash guides only in the cavern, in recreational gear. Going further into the cave of the Old Freetown system needs a cave certification, sidemount and a cave guide (Cristina Zenato). Never without a local guide.
Hurricane Dorian (2019) caused a ceiling collapse in the Mermaid cavern section of the system: expect changed passages.
Profile and sections

The entrance is a shallow pond (~1.3 m); right behind it lies a chamber ~12 m high with clear water (showcaves.com). It is one of Grand Bahama's best-decorated caves: a large room with stalactites, stalagmites, soda straws, flowstone and dogtooth-spar crystals.

Practical: Calabash charges $220 (1 diver) or $200 pp (2+), park fee extra.

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

Entrance pool hidden in the forest, hard to find. Always with a local guide: in the cavern Calabash Eco Adventures or Cristina Zenato; the cave beyond it (the Old Freetown system) only with a cave certification, in sidemount and with a cave guide (Cristina Zenato). Park fee $15 (Calabash).
