A sea of walls, wrecks and marine parks: Hol Chan, Palancar, Bloody Bay Wall, Bonaire shore tags, and a Kittiwake that was sunk on purpose.
Key takeaways

Read first Water sports carry drowning, pressure and medical risks. Use certified instruction, check conditions, and never treat depth or time tables as personal clearance.
How to use this guide Match skill to site Start in controlled water, then add current, depth and night only with training.Verify agency path PADI, SSI, CMAS and national programs differ on medical and depth rules.Expert voices Conditions beat gear: abort early when visibility, current or buddy signals change. Dive instructor — Site briefings Quick answers Do I need a medical form? Most agencies require a questionnaire or physician clearance before confined or open-water training.
How do seasons affect sites? Visibility, current, temperature and wildlife access change by month — check local charts and operators.
Key data Band Teaching use Depth band Agency training limits — not a personal clearance. Visibility Site and season dependent; abort when buddy contact is lost.

Buddy requirement? Recreational systems usually train with a buddy. Solo requires extra training and local permission.

The Caribbean is a sea of islands and reefs whose recreational map is not one country: Belize's Hol Chan, Cozumel's Palancar, Little Cayman's Bloody Bay Wall, Bonaire's shore-tag park, and purpose-sunk wrecks such as USS Kittiwake (2011). Bonaire National Marine Park dates to 1979; Hol Chan Marine Reserve to 1987.
Wow factor is high among places, a step below Raja Ampat and Palau in this atlas. Accessibility is the highest of the destination set: short flights from North America and many shore entries. Seasonality is moderate (hurricane window, not a monsoon close-out). Risk is moderate: boats, current on walls, and the usual reef manners.
This chapter is a place atlas, not a cruise itinerary, not a certifying agency, and not a live briefing. Park tags, hurricane centres and the day's wind override any sentence here.
Educational atlas, not a certifying agency and not medical or rescue advice. Local parks, skippers and instructors have the last word on conditions.

Frequently asked questions 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.
Stingray City? A Grand Cayman sandbar where rays were habituated to boats. Ethics and park rules have tightened; it is not a wild chase product.
Live briefing? No.
