Safety · Destination Guide
Cold Atlantic bays, a dramatic Donegal coast and world-class technical wreck history.
This is a cold Atlantic coast with tidal inlets and offshore technical wrecks, not a sheltered tropical dive park. Use qualified, insured operators and never extrapolate a safe site from an attractive beach or a booking page. Confirm site and heritage permissions, forecast, group experience, emergency oxygen, communications, rescue cover and post-dive travel. Ireland's Coast Guard coordinates marine emergencies on 112 or 999 and VHF channel 16. Letterkenny University Hospital provides regional emergency care; the National Hyperbaric Medicine Unit at University Hospital Galway treats decompression emergencies via medical coordination.
Call 112 or 999 and ask for Coast Guard if there is a marine emergency; boat crews can use VHF channel 16. If decompression illness or arterial gas embolism is suspected, activate emergency services immediately, provide first aid oxygen if trained and equipped, follow the dispatcher and operator emergency plan, and do not arrange uncoordinated private transport to a chamber. Letterkenny University Hospital is the regional acute hospital (main line +353 74 912 5888). The National Hyperbaric Medicine Unit is at University Hospital Galway (hospital switchboard +353 91 524 222); for emergencies its published instructions ask callers to request the third on-call anaesthetist. Transport decisions belong with the emergency medical service, not a guide estimate. A diver with new, unexplained symptoms after a dive needs urgent clinical assessment even if the dive felt routine.
Cold water and hypothermia
The Irish Coast Guard warns that Irish waters are cold throughout the year; use suitable thermal protection and account for cold surface intervals.
Rapidly changing Atlantic weather
Strong winds, swell, poor visibility and site swaps can close boat departures even in summer. Check Met Eireann and the skipper close to sailing.
Deep wreck decompression hazards
Mevagh technical trips list depths beyond sport-diving limits. Require appropriate technical training, redundant equipment, gas planning and a response plan; never equate an ordinary wreck specialty with full technical competence.
Protected wreck permits
Diving at protected underwater heritage sites requires a licence from the National Monuments Service; taking artifacts is separately regulated.
Ireland automatically protects wrecks more than 100 years old and archaeological objects underwater; regulated diving, surveys and any disturbance require appropriate permission. Do not move artifacts, attach line to vulnerable historic structures or search with metal detectors without the necessary legal consent. Keep fins clear of fragile seabed life, avoid ghost gear and report abandoned nets through qualified channels rather than attempting risky independent removal. Basking sharks are protected wild animals. Do not chase or solicit deliberate in-water wildlife approaches. Follow national and local coastal habitat rules, use designated routes, leave nests and birds undisturbed and check the EPA's bathing-water notices before swimming.
Do Not Do This
Avoid entering when cold water and hypothermia. Confirm local briefings before committing.
