Zakynthos

Dive mornings are usually easiest before wind and boat traffic build. Carry a DSMB, use a computer, keep profiles conservative, and avoid flying for at least 18 to 24 hours after diving based on your dive schedule and agency guidance. For caves and swim-throughs, use a trained guide, torch, and good buoyancy, and never enter overhead environments beyond your training. Ask each operator about oxygen, radio or phone coverage, evacuation route, and nearest appropriate hyperbaric plan.

Zakynthos General Hospital Agios Dionysios is the island's public hospital, with private clinics in resort areas for minor urgent care. In a life-threatening emergency call 112 first; for sea emergencies use 108; for suspected DCI, give oxygen if trained, keep the diver hydrated and supine unless breathing issues require otherwise, and contact DAN Europe or your dive insurer for hyperbaric triage and evacuation coordination. Confirm current chamber arrangements with your operator before diving.

The National Marine Park of Zakynthos protects loggerhead turtle habitat and other coastal ecosystems. Within the park, motorized watersports, spearfishing, recreational fishing methods, and some professional fishing activities are restricted or banned in designated zones. Boat speed and mooring rules apply. On nesting beaches, visit only during allowed daytime hours, keep beach activity within 5 m of the seafront where required, avoid dogs and vehicles, never dig, never use bright lights at night, and never touch turtles, nests, or hatchlings.
