Hol Chan cut and shallows
Ambergris Caye, Belize · 1-8 m · variable · year-round, wind
A 1987 marine reserve at a reef cut. The textbook Caribbean snorkel park; Shark Ray Alley is a nearby, more argued add-on.
These are famous, mapped sites. Wind and hurricane calendars change; parks publish the day. Depths are typical published bands, not a live plan.
A tagged shore or a reserve shallows is the correct first Caribbean water.
Points
Palancar (gardens / caves / horseshoe)
Cozumel, Mexico · 10-30 m · often 20-30 m · year-round, current
A drifted reef complex on the Yucatan current. Gardens are kinder; deeper walls are a later exam. Marine-park rules.
Bloody Bay Wall
Little Cayman · 5-30 m+ · often 20-30 m · year-round, weather
A wall that begins in snorkel-shallow water and drops into blue. A Caribbean buoyancy classroom with a famous name.
USS Kittiwake
Grand Cayman · 4-20 m · often 20-30 m · year-round
A purpose-sunk 2011 artificial reef, shallower and more planned than a war grave. Still a wreck: cutters, lights, no souvenirs.
Bonaire Salt Pier
Bonaire · 5-15 m · often 15-25 m · when open / no ship
A working pier that is also a fish-and-light site, closed when a salt ship is in. The park tag still applies. Shore culture.
Stingray City sandbar
Grand Cayman · 1-2 m · variable · year-round, crowd
A habituated ray sandbar. Ethics and rules have tightened; it is a manners exam, not a grab-and-grin.
Tobago Cays Marine Park
St. Vincent and the Grenadines · 1-8 m · variable · dry months popular
A Grenadines park of cays and turtles. Anchoring and turtle-distance rules; a sailing-week snorkel more than a scuba wall.
Devil's Grotto
Grand Cayman · 5-12 m · often 15-25 m · year-round
A shore-accessible coral-canyon site near Georgetown, also dived on scuba. Boats, entries, and a reminder that Cayman is not only walls.
Tips
- Tag before the giant stride — Bonaire and Hol Chan mean it.
- Gardens before the deep Palancar drop — Current plus depth.
- Ask if Salt Pier is open — A ship in the berth closes the site.
- Rays are not props — The sandbar brief is the whole point.
The Caribbean is a cut, a wall, a tag and a planned wreck. It is not one island with one postcard.
