About Prison Gardens
Prison Gardens is a sheltered southern-atoll boat dive on the lee side of Prison Island, with plate and hard coral, monitoring buoys, and long schools of bigeye trevally moving through the blue. Southerly winds make it a useful protected-water option when outer sites are rougher, and the calmer summer window turns it into an easy, fish-heavy cruise along the atoll edge. It suits divers who want a quiet reef day with clear structure rather than drama.
Safety & Access
Site Conditions
Sharp coral
Safety Notes
Keep buoyancy tight over plate and hard coral, and treat the lee-side shelter as a comfort aid rather than a free pass.
Access Restrictions
Boat access only; plan it as a guided Cocos atoll dive that is used when southerly winds make exposed outer sites less comfortable.
Legal Notes
Follow Cocos Keeling Islands Marine Park guidance and the local operator briefing.

Scuba Diving
Lee-side boat dive with plate coral, hard coral, and trevally schools along the southern atoll edge.
Freediving
Not a freedive-first site; the boat access and coral/trevally profile suit scuba better than breath-hold touring.
Snorkeling
Not a snorkel-only pick; the reef is best appreciated as a planned scuba boat dive.
