Entry

Yellowtail snapper (Ocyurus chrysurus)

Shore and boat entries vary by site. We list only rules we can cite from official sources; entry points, depths and currents will be added once we can verify them.

Local rules (cited)
  • The DoE has installed public moorings to protect reefs from anchor damage. Use a mooring instead of anchoring whenever possible; it is an offence to damage coral anywhere in Cayman waters. Cayman Islands DoE · Public Moorings
  • The maximum stay on a public mooring is 3 hours. Do not use moorings in winds of 25 knots or more. Cayman Islands DoE · Public Moorings
  • Marine Park zones carry their own rules (for example, no taking of marine life in Marine Reserve zones and no SCUBA diving in No Diving zones without permission). Check the zone with the DoE app or brochures. Cayman Islands DoE · Marine Parks
  • Wildlife Interaction Zones are the only places in the Cayman Islands where you may legally feed or interact with marine life. Cayman Islands DoE · Marine Manners

Plan & prepare

  1. Read the official marine forecast the night before.Offshore, wind and sea state decide the day.
  2. Check the cited local rules above and pay any park fee before you dive.[Placeholder: verified operator list to come]
  3. Study this month's species above.You'll recognise more when you know the names.
  4. Hands off, fins up, buoyancy dialled. Log what you see.Your sightings can become tomorrow's open data.
