Kinsale and Cork South Coast

Scuba

• Match certification, fitness and cold-water competence to actual site and conditions, not generic operator marketing. Insist on a suitable buddy, sufficient gas and an emergency plan; arrange guide if unfamiliar with Irish seas.
• Use thermal protection (7mm suit with hood/gloves or fitted drysuit after training), ascent planning, an SMB, navigation and a surface support/watch appropriate to the operator. Confirm onboard oxygen and first-aid provisions rather than relying on a website statement.
• Bream Rock has operator-reported strong current and slack-water requirements. Ling Rocks are deep/offshore and not a casual Open Water site. A cavern, wreck opening or arch is an overhead hazard even when described as scenic.
• Protected wrecks require NMS licence approval and any site-specific restrictions. No removing artifacts, metal detecting or recreational simply-looking exception.

Snorkeling and Freediving

• Do not snorkel or breath-hold alone; use trained buddy/rescue capacity, high surface visibility and a known exit. No hyperventilation before breath holds. Freediving rescue training and monitoring are distinct from scuba buddy norms.
• Avoid working harbor channels and exposed beach entries. Stop for cold stress, fatigue, poor visibility, changing tide or surf.
• At any beach, use the latest EPA and local authority notices. The monitoring season being over does not certify water safe.

Before and After a Dive

• Plan surface intervals and conservative no-fly timing with actual exposure and guidance such as DAN recommendations; even published minimum intervals are not guarantees against decompression illness.
• Confirm that operator crew, shore contacts and emergency responders know the intended site, number of divers, last-dive profile and return time.

For suspected decompression illness, serious breathlessness, neurological symptoms, injury or cold-water collapse: call 112/999 first, make the dive profile available and follow emergency dispatcher/clinician instructions. If trained equipment and a suitable responder are on scene, administer emergency oxygen as instructed by established dive first-aid protocols; do not delay emergency services while searching for a chamber. Cork University Hospital Emergency Department is an identified major local emergency care option at Wilton Road, Cork, but this guide does not verify a hyperbaric chamber at that hospital, referral eligibility or transport time. DAN Europe offers 24/7 diving-medical support, secondary to emergency activation, at +39 06 4211 5685. Have insurance policy numbers and recent gas/depth/timing profiles ready. Do not self-drive to an assumed compression chamber.

Bird and Habitat Protection

• Sovereign Islands Special Protection Area is designated for breeding cormorants. Old Head of Kinsale SPA covers important kittiwake and guillemot interests. These are protected bird areas, not generic marine-park fee zones. Observe permitted approach/landing rules and avoid disturbance of breeding cliffs or stacks.
• Oysterhaven includes documented seagrass beds, which support small marine life; do not anchor in, kick through or collect from the bed.
• Photograph rather than handle nudibranchs, anemones, fish or seals. Keep distance from any sharks, seals, dolphins or nesting seabirds; no chase, feeding, touching or promise of encounters.

Historic and Visitor Conduct

• Irish underwater heritage law automatically protects wrecks over 100 years old, and NMS requires a licence to recreationally dive protected heritage. Do not remove objects or penetrate wrecks without relevant training and legal approval.
• Take litter away, use established access, avoid private Old Head land and report marine hazards or pollution through the appropriate authorities.
