Boat access and exposed conditions make a local operator the normal way to run the site.
Sister Bank is an offshore granite-boulder dive with swim-throughs and exposed-water drift sections. It suits experienced divers who want moving-water planning, shaped rock, and frequent shark-and-ray life rather than a sheltered reef cruise. Boat timing matters because the pickup follows the drift and the sea state can change the route.

Key Hazards
Safety Notes
Plan for current management, keep the team together through the swim-throughs, and respect the exposed offshore setting.

Community notes to help plan your visit.
Scuba Diving
Granite boulders, swim-throughs, and drift sections make this a rewarding current-aware scuba site.
Freediving
Shallow boulder sections can work for experienced freedivers, but current and drift pickup make scuba the safer default.
Snorkeling
Not a snorkel-first site; the exposed offshore setting and passages are better managed from a boat dive.
