About Sister Bank
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.

Scuba Diving
Granite boulders, swim-throughs, and drift sections make this a rewarding current-aware scuba site.

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.
