Quick answers
Which local rescue or training agency should I check first?
Use the local lens: coastguard/federation norms and the shop briefing for that bay — not a blog visibility claim.
What is Hol Chan?
A Belize marine reserve (1987) at a cut (chan) in the reef off Ambergris Caye, often paired with Shark Ray Alley. A textbook managed snorkel park.
Palancar?
A Cozumel reef complex of walls and gardens, drifted on the Yucatan current. Marine-park rules and a 1996 grounding history sit under the fame.
Bloody Bay Wall?
A Little Cayman wall that starts in shallow water and drops into deep blue, a Caribbean wall-teaching site.
Why is Bonaire different?
A 1979 marine park, a shore-tag system, and a no-anchor culture that made the island an etiquette laboratory.
Kittiwake?
A US Navy submarine-rescue ship sunk in 2011 off Grand Cayman as an artificial reef, shallower and more planned than a war grave.
The method is a park ticket (Bonaire tag, Hol Chan, Cozumel park), then a choice among a cut snorkel, a current wall, or a purpose-sunk wreck. Cruise-ship hours are a crowd condition, not a skill.
A first day belongs on a Bonaire shore or a Hol Chan shallows, not on a deep wall drop.
Steps
- Pay the tag and hear the park
Bonaire, Hol Chan, Cozumel each have a sentence.
A cruise wristband is not a park brief.
- Enter on sand or a ladder
Never on living coral. See reef-etiquette.
Bonaire yellow stones mark many entries.
- Drift walls as briefed
Palancar and Bloody Bay are current products.
SMB if the boat says so.
- Wrecks: planned vs grave
Kittiwake is a 2011 classroom. War wrecks are a different manners.
- Rays and sharks: distance
Shark Ray Alley and Stingray City are habituated sites with tightening rules.
No grabbing.
- End before the cruise tender scrum if possible
Crowd is a condition.
Morning is the Caribbean craft.
Skills
- Shore-entry navigation (Bonaire) — A map, a stone, a swim out.
- Drift composure — Cozumel craft.
- Wall buoyancy — Bloody Bay starts shallow and does not stay shallow.
- Park-tag literacy — The unglamorous skill.
- Saying no to a bread-ball boat — Feeding is a failure mode.
Progression
- Hol Chan shallows or Bonaire shore — The classroom.
- Palancar gardens or Kittiwake — A wall or a planned wreck.
- Bloody Bay Wall — After buoyancy exists.
- Tobago Cays or a hurricane-season skip — Optional, weather-bound.
Common mistakes
- Treating the sea as one island — It is a province of parks.
- Standing on Hol Chan coral — The photo the reserve was written against.
- Grabbing a stingray — How ethics briefs get longer.
- Deep wall on a first Cozumel drift — Current plus depth.
The method is a tag and a morning. The deep wall is a later exam.
