Rathlin Island

About Rathlin

Rathlin is the only inhabited offshore island in Northern Ireland. It lies about six nautical miles north of Ballycastle, an L-shaped piece of basalt and chalk roughly four miles east-west and two-and-a-half north-south. The high point is Slieveard at 134 metres. The population at the last census was 141. There is one road, one shop, one pub and three lighthouses.

The boat from Ballycastle takes 25 minutes on the fast catamaran and 45 minutes on the conventional ferry. Both run year-round, weather permitting. Most visitors arrive in the morning, spend the day, and leave on a late-afternoon sailing. A few stay overnight at the guesthouses or the small campsite at the harbour, which is a different experience entirely. The island after the last boat goes is very quiet.

The headline visit is the RSPB West Light Seabird Centre at the far western tip. The "upside-down" West Lighthouse here is built down the cliff face, with its lamp room at the bottom of the structure rather than the top — a 1912 engineering oddity that turned out to be exactly the right design for a lamp meant to be seen from low on the sea below. The viewing platform inside the lighthouse looks out over a series of basalt sea-stacks where common guillemots, kittiwakes, razorbills, fulmars and (from April to mid-August) puffins nest in their tens of thousands.

The other two lights are the East (Altacarry Head) Light, on the north-east corner, and Rue Point at the south. East Light is famous for being the place where Marconi first established commercial wireless telegraphy across water, in 1898, signalling to Ballycastle. Rue Point is the smallest of the three. All three are still in service.

Beyond the birds, the island has the small Boathouse Visitor Centre at the harbour, with exhibitions on Rathlin's history including the 1575 massacre, the wreck of HMS Drake in Church Bay in 1917, and the cave on the north shore where Robert the Bruce sheltered in 1306 — the cave from which the spider story comes, whether or not the spider was real.

Essential information

Book ferries early

Sailings fill up in summer, particularly the morning out and late-afternoon return. Book online with Rathlin Island Ferry, ideally a few days ahead.

When for puffins

Late April through mid-August. Mid-May to early July is the peak. The colony leaves by late July and the cliffs empty fast.

Walking the West Light

Roughly 4 miles return on tarmac road from Church Bay. Allow 75–90 minutes each way at an easy pace. In season, a community minibus runs the same route — book at the Manor House.

Weather

Rathlin is exposed and crossings are weather-dependent. Sailings can be cancelled at short notice in winter. Check the operator's status before driving to Ballycastle.

Dogs

Welcome on ferries and on the island, on leads. Keep well clear of ground-nesting birds in season.

Refreshments

The Manor House at the harbour and McCuaig's bar serve food. Hours limited — pack a flask for the West Light walk.
