Rathlin Island — Ferry to NI's only inhabited offshore island for puffins, seals and an upside-down lighthouse.
What you do: Ferry crossing then exploring the island on foot, by bike or by minibus; cliff-top seabird watching; the upside-down lighthouse; seals at the harbour.
Difficulty: Moderate. Easy ferry and harbour, but 4.5 miles to the West Light and 98 steep cliff steps down to the puffin platform.
Age / height: No formal limits, but check age and supervision rules and the steps are unsuitable for very young or unsteady walkers; keep children close near cliffs.
Booking: Book the ferry online in advance, both ways, ideally at least 30 minutes before departure and earlier in summer. Seabird Centre is pay on arrival in season.
Come ready: Warm windproof layers, waterproofs, sturdy shoes, packed lunch and water, binoculars, sun cream. The weather changes fast.
Weather: Exposed Atlantic cliffs and open sea. Ferries can be cancelled or altered at the skipper's discretion in high wind; supervise children near cliff edges and steps.
Plan your visit
Puffins, cliffs and the upside-down lighthouse
The headline sight is the RSPB West Light Seabird Centre on the island's western tip, open spring to late summer. From the harbour it's 4.5 miles, so most families take the Puffin Bus (a paid return minibus), hire bikes, or walk it. At the centre you go down 98 steps to a viewing platform set right against the cliffs, where puffins, kittiwakes, guillemots, razorbills and fulmars nest in their thousands. The 'upside-down' lighthouse is the other star: built in 1919 with its lamp at the base of the cliff and the keepers' quarters above, because the clifftop was too often lost in fog. Peak puffin numbers are May and June; the colony thins out by early August.

Getting there
Rathlin Island is at Rathlin Island, Co Antrim, BT54; ferry departs Ballycastle ferry terminal, Bayview Road, Ballycastle, BT54 6BT.. Public car parks in Ballycastle by the ferry terminal (seasonal charges). No car needed on the island unless you pre-book a vehicle space. Tap below for directions.
Rathlin is Northern Ireland's only inhabited offshore island, an L-shaped scrap of land about 6 miles off Ballycastle with a small year-round community at Church Bay. It has three lighthouses, sea-bird cliffs and a long human history, from early Christian settlement to the 1575 massacre at the island's castle.
The RSPB manages the West Light Seabird Centre, where thousands of puffins, guillemots, razorbills, kittiwakes and fulmars breed on the western cliffs each spring and summer. The Rathlin West Light itself was built in 1919 and is famously 'upside down': because the clifftop sat in fog, engineers set the light at the base of the cliff with the keepers' quarters above it.
Local boat operators run the ferry from Ballycastle under the Department for Infrastructure's island service, with a summer and winter timetable. Once ashore, a privately run Puffin Bus, bike hire and walking trails connect the harbour to the lighthouses and viewpoints.
