Safety · Destination Guide
Tiny island, giant walls, and a marine park pace set by the reef
Updated Apr 26, 2026 • 32 sources
Little Cayman feels relaxed, but the safety margin comes from conservative wall diving, careful small-island logistics, and strict conservation behavior. Plan for remote-island medical limits, follow operator briefings, and keep marine life interactions passive.
Set a maximum depth before every wall dive, stay within no-decompression limits, and check gas more often than the visibility makes you think you need to. Carry an SMB, keep clear of boat traffic, and do not descend into swim-throughs unless you are trained, briefed, and comfortable. Avoid flying too soon after diving: DAN recommends at least 12 hours after a single no-decompression dive and at least 18 hours after repetitive or multi-day no-decompression diving. Use longer intervals after decompression, mixed gas, or symptoms. Report suspected decompression illness immediately and do not try to self-treat by waiting overnight.
Little Cayman has a local health centre, but serious dive injuries, major trauma, and recompression needs may require evacuation or transfer to Grand Cayman. Cayman Hyperbaric Services operates the recompression chamber at George Town Hospital and is available on-call 24 hours, 365 days. Carry dive accident insurance, travel insurance that covers evacuation, and printed emergency contacts because cell signal and transport timing can vary.
Wall depth creeps quickly
Little Cayman's walls can feel benign because the reef top is shallow and visibility is high. Set a max depth, monitor gas and NDLs, and do not follow animals down the drop-off.
Storm season affects small-island logistics
From June 1 to November 30, tropical systems can disrupt flights, boats, groceries, and prepaid plans. Buy travel insurance and build schedule buffers.
No gloves and no take
Normal diving and snorkeling should be hands-off. Do not wear gloves, touch coral, collect shells, or take marine life while scuba diving. Operators and rangers take these rules seriously.
Iguanas and narrow roads
Drive and cycle slowly, especially near beaches and warm pavement. Rock iguanas can move unpredictably, and visitors should never feed or herd them.
Follow Cayman marine park rules on every dive, snorkel, and boat day. Do not touch coral, stand on reef, take marine life while scuba diving, collect shells or coral, dump waste, or wear gloves for normal diving and snorkeling. Use public moorings correctly instead of anchoring near reef, and follow all Bloody Bay, Wildlife Interaction Zone, shark feeding, turtle nesting, and Nassau grouper spawning guidance. Keep beaches dark and quiet during turtle nesting season, give iguanas road space, and report turtle tracks, nests, hatchlings, damaged moorings, or marine offences through the appropriate official channels.
Do Not Do This
Avoid entering when wall depth creeps quickly. Confirm local briefings before committing.
