Safety · Destination Guide
Two shores, clear Adriatic water, protected wrecks and wine-country surface intervals
Treat this as boat-intensive Mediterranean diving with deep options, active shipping lanes, seasonal thermoclines and weather-driven site selection. Use a registered operator, carry appropriate accident and evacuation insurance, and keep the first and last travel days conservative. Protected wrecks and archaeological material are legal as well as conservation responsibilities. Posidonia oceanica seagrass is strictly protected in Croatia and can be damaged by anchoring, fin contact and careless shore use.
For suspected decompression illness, arterial gas embolism, serious barotrauma or loss of consciousness, provide oxygen if trained, call 112 or maritime rescue on 195, state that it is a diving emergency, preserve the computer and profile, and contact the diver's insurer or DAN. Do not recompress in the water, do not fly, and do not drive a deteriorating patient long distances without emergency coordination.
Korcula, Orebic, Ston and other settlements have local medical access for initial assessment, while definitive specialty care may require transfer to a larger mainland hospital. Chamber location, readiness and acceptance pathways should never be assumed from an old directory. Before diving, ask the operator for its current emergency assistance plan, oxygen provision, evacuation route and the hyperbaric facility used for that day's site. In a serious event call 112, or 195 when rescue at sea is required, and identify the incident as dive-related. Carry a European Health Insurance Card when eligible, but do not treat it as a replacement for dive accident, evacuation and trip interruption insurance.
Protected wreck and archaeology rules
Some wrecks and underwater cultural sites require a specifically authorized dive center and Ministry-linked permission. Do not remove, move or disturb finds. Leave an unexpected artifact in place and report it through the operator or competent authority.
Boat and ferry traffic
The Peljesac Channel and approaches to Korcula are active transport routes. Follow the boat crew's ascent point, deploy an SMB when instructed, stay clear of harbours and ferry tracks, and never make an unmarked independent ascent.
Fast-changing Adriatic wind
Bura, jugo, frontal weather and the summer afternoon maestral can produce chop, rough crossings and site swaps. Use the DHMZ marine forecast, not a general phone icon, and let the local skipper cancel or choose a leeward alternative.
Thermoclines and deep exposure
Warm surface water can conceal a much colder layer at depth. Garden and the deeper wrecks also compress no-decompression time. Wear enough exposure protection, monitor gas and computer limits, and avoid using a warm beach reading as a deep-dive forecast.
Posidonia seagrass meadows are a protected habitat and nursery area. Use established moorings where available, never ask a skipper to anchor in seagrass, maintain buoyancy above plants and keep fins off the bottom. On reefs and wrecks, do not touch gorgonians, feed wildlife, collect shells or disturb resting animals. Croatian rules require archaeological finds to remain where discovered and to be reported; photography is not permission to handle an object. Minimize single-use plastic, refill water where practical and choose operators that carry oxygen, brief low-impact diving and use legal moorings. Spearfishing, collecting and scuba are governed separately, so never assume a recreational dive booking authorizes extraction.
Do Not Do This
Avoid entering when protected wreck and archaeology rules. Confirm local briefings before committing.
