The Four Lights Swim Series

Four provinces. Four lighthouses. Four swims.

An open-water challenge around the four corners of Ireland — each crossing more than ten kilometres, independently certified, each anchored to a single light. Collect all four to hold the Four Lights.

The idea

One lighthouse per province. One long swim to each.

Ireland has four provinces. The Four Lights sets one long open-water swim in each — a crossing between a lighthouse standing off the coast and the mainland behind it. Every crossing is accredited over more than ten kilometres.

The lighthouse is the fixed point; everything else is the swimmer's. You may swim in either direction and come ashore anywhere on the mainland, so long as the swim begins or ends at the light and is certified over the full distance. There is no set course and no set day — only the light, the water, and the crossing you make of it.

The four lights

One light in each province. Four crossings to hold them all.

Cork mainland ≈ 20 km Read the swim 02 Connacht Black Head A limestone light on the edge of the Burren, watching the liners in. Black Head Co.

Wicklow mainland ≈ 20 km Read the swim 04 Ulster Altacarry Head The Sea of Moyle — Bruce's spider above, the Children of Lir below. Altacarry Head the Co. Antrim mainland ≈ 12 km Read the swim

The symmetry

Four lights, four provinces — a map of Ireland drawn in navigation lamps.

The series was built around a coincidence of geography that felt too neat to ignore. Take one significant light from each province and they fall, roughly, to the four points of the compass: Fastnet in the deep south of Munster, Black Head on the western edge of Connacht, the Kish off the eastern capital in Leinster, and Rathlin's East Light in the north of Ulster.

Trace them and you have drawn the outline of the whole island in four crossings — the country reduced to its four hardest edges, and the swimmer asked to touch each one. That symmetry is the heart of the series. It is what turns four good swims into a single thing worth finishing.

The challenge

No calendar. No mass start. You plan the swim, a third party certifies it, and you claim your light.

  1. 1

    Plan your attempt

    There is no fixed date and no mass start. Choose your window, your direction and your line, and engage a recognised pilot to put you safely on the water.

  2. 2

    Swim it certified

    Every crossing must be independently observed and certified by a recognised third-party authority — in Ireland, typically the ILDSA. The Four Lights is not affiliated with them; we simply require their standard.

  3. 3

    Tell us first

    Notify us of an intended attempt before you go, so the swim can be recognised toward the series.

  4. 4

    Claim your light

    After a successful crossing, submit your certification to claim the light — within three months of the swim. Collect one to be on the board; collect all four to hold the Four Lights.
