Jardines de la Reina
Main liveaboard window outside the peak storm season.
Jardines de la Reina ('Gardens of the Queen') is a 250km reef system off Cuba's southern coast — strictly protected, accessible only by liveaboard, with the densest shark and grouper population in the Caribbean. Often called the healthiest Caribbean reef.
Good season
November–June. Closed in summer hurricane season.
Trip duration
7-night liveaboard from Júcaro.
Dive style
Wall and reef diving with mild-to-moderate current; baited shark dives.
Dive level
Advanced recommended.
Reef health
What you’ll actually findSome loss since the 2010s, but the reef still has plenty to dive. Pick depth and shoulder-season carefully.
Coral reef health
How is this calculated?On current trend, no live coral by ~2214. Losing about 0.2% cover per year — roughly 190 years of reef left to see if nothing changes.
Heat stress right now
No abnormal heat right now. Corals stay coloured.

What to expect on a dive
One of the Caribbean's best-preserved reefs thanks to decades of MPA protection and restricted diver access. Apex predators still present.
Sources, methodology, and the raw numbers
Raw observed numbers
- Coral cover: 38% (survey Sep 2024, Jardines de la Reina MPA reef survey)
- Bleached: 8%
- Recent mortality: 2%
- Jardines de la Reina MPA — observed condition reflects the stable regional pattern.
Raw thermal numbers
- NOAA CRW alert level: No stress
- Degree Heating Weeks: 0 °C-wk
- SST anomaly: +1.4 °C
How we summarise this
Observed coral cover, bleaching, and mortality come from named in-situ surveys with a stated date and method — they describe one snapshot of one reef and do not extrapolate to neighbouring sites. Current thermal stress is satellite-derived from NOAA Coral Reef Watch at ~5 km resolution; it indicates risk, not observed coral damage. We deliberately separate observed condition, current thermal stress, and projection — and we never publish a projection without a documented model and uncertainty.

What you can do
Jardines de la Reina is the Caribbean's largest no-take reserve; permit-only access. Caribbean MPAs (Cayman, Saba, Bonaire, Bonaire, Cuba JdR) are some of the world's best-managed. Pay the conservation tag fee at entry and join a lionfish cull if offered.
Protection status sourced from Protected Planet / WDPA and refined with Marine Protection Atlas. Fishing pressure proxy is Global Fishing Watch AIS data. See the methodology for what these sources can and can’t prove.

“Caribbean reefs as they looked in 1950. Cuba's diving secret has been the embargo.”
