Off Donaghadee, a tall black tower banded in white rises above the rocks of the Copeland Islands. Mew Island Lighthouse has guarded the approaches to Belfast Lough since 1884. Around the station’s low buildings, the sea fills almost the entire landscape; the lighthouse’s vertical profile is all the more striking because the island itself sits low and unobtrusively on the horizon.
This lighthouse in County Down, Northern Ireland, holds another surprise: its former monumental optic can now be seen in Belfast. There are therefore two ways to experience it: by boat, to admire the tower in its setting, then on land, to see the lighting mechanism that kept it operating for so long. Do not, however, plan to climb the lighthouse: no regular public tours of the tower are advertised.
Before Mew Island, ships navigated by a light installed on Lighthouse Island, also known as Lesser Copeland Island. As maritime trade and steamships developed, a more suitable location was sought. Work on the new station began in 1882, to designs by engineer William Douglass. Mew Island Lighthouse entered service on 1st November 1884, while the light on Lighthouse Island was extinguished.
These two neighbouring islands should not be confused: the name Lighthouse Island refers to the former station, while the large tower that remains in operation stands on Mew Island.
The lighthouse forms part of a larger complex that includes the former keepers’ cottages, a building associated with the fog signal and a former gas-production installation. These outbuildings are a reminder of the scale of work required to maintain an offshore light. Northern Ireland’s heritage listing protects the whole complex, not just the tower.
The masonry incorporates stone quarried on the island, supplemented by granite elements from the Newry area. The tower is rendered and stands out for its black profile, broad white band and pale lantern. The official register of historic buildings in Northern Ireland highlights the coherence of this maritime station, built between 1882 and 1884.
From a boat, take time to look at the low buildings at the foot of the lighthouse. Their scale makes it easier to appreciate the dimensions of the tower, which rises to 37 metres. Mew Island is as much a piece of industrial history as it is a photogenic silhouette.
The light was electrified in 1969. On 29 March 1996, automation led to the permanent withdrawal of the keepers. The station remains operational, and its navigational aids are monitored remotely. According to specifications published by Irish Lights, the light now displays a group of four white flashes every 30 seconds.
The keepers’ departure did not turn Mew Island into an abandoned monument. Its maritime function continues, which is also why the island should not be treated as a freely accessible tourist site.
In 1928, Mew Island received a remarkable two-tier optical apparatus, created by adapting equipment from Tory Island Lighthouse. Its large Fresnel lenses concentrate the light into powerful beams: their scale and precision offer an insight into the ingenuity employed before modern equipment.
Removed in 2014 when the lighthouse was modernised and converted to solar-powered LED lighting, the optic was preserved. Since 8 March 2018, it has been displayed on Belfast’s Titanic Walkway under the name The Great Light. It is a complementary stop for seeing up close an element that would be difficult to make out from the sea. The lighthouse remains the main subject here; a detailed look at the optic deserves a separate stop in Belfast.
To see the lighthouse from the water, one practical option is the Copeland Islands cruise offered by Island Boat Charters Donaghadee, aboard the M/V Island Lady. Departures are from the historic steps of Donaghadee Harbour, and the advertised route lasts around 1 hour 30 minutes.
The excursion passes near Great Copeland Island, then Old Lighthouse Island, before offering views of Mew Island Lighthouse. This is a cruise with no landing, not an interior tour of the lighthouse. The route remains subject to sailing conditions and the skipper’s decision.
The islands also add a wildlife dimension to the trip: seals and several species of seabird may be spotted. Birdlife varies by season, while dolphin and porpoise sightings can never be guaranteed. Keep binoculars to hand, without spending the entire trip with your eye fixed to the camera.
When we checked in October 2026, the operator listed a fare of £25 for ages 14 and over and £15 for children aged 2 to 13 for the sightseeing cruise. These prices apply to the boat trip; they do not provide access to the tower.
The FAQ indicates a usual season from late April to late September, although additional dates may be announced. The actual schedule is published on the operator’s social media channels. Confirm the trip directly before travelling, along with booking, payment and cancellation arrangements. Outside the usual season, do not rely on a departure without prior confirmation.
Allow around two hours at the harbour and at sea, including time for boarding around the advertised 90-minute sailing. Ask for the precise check-in time and meeting point: a harbour may have several sets of steps and boarding areas.
Even in fine weather, bring a windproof jacket, a warm layer and sturdy shoes. Protection from sea spray is useful for your phone or camera. A telephoto lens will allow you to frame the tower without needing to pass particularly close to the rocks; adapt your photography to the boat’s movement and the crew’s instructions.
If you are travelling with young children or someone with reduced mobility, ask the operator before booking about the access steps, any assistance available and the facilities provided. For a child under two, specifically ask whether boarding is permitted: the published fare begins at age two. If you are prone to seasickness, also ask about the expected conditions and seek advice from a pharmacist if necessary.
The lighthouse’s GPS coordinates locate the station on the island. To reach the excursion by car, set Donaghadee Harbour as your destination, then follow the meeting point confirmed by the operator. Allow time to find permitted parking and walk to the quay.
Donaghadee Lighthouse, at the end of the harbour pier, is a different structure. You can admire its exterior on a walk ashore, subject to conditions on the pier. Mew Island Lighthouse lies offshore in the Copeland Islands: it cannot be reached via the pier.
For a well-organised day, allow time in Donaghadee before or after the boat trip and have a land-based alternative in mind if the excursion is cancelled. The harbour and promenade make for a pleasant maritime stop; Mew Island’s former optic, meanwhile, awaits in Belfast to extend the experience without depending on a crossing.

Check the opening hours and admission requirements before you leave, especially during peak season or on Irish public holidays.
No regular public tours of the lighthouse. To view it from the sea, Island Boat Charters listed, in October 2026, the approximately 1 hour 30 minute cruise at £25 for ages 14 and over and £15 for ages 2 to 13.
