📍 Donaghadee, Down

🏛️ Attraction

Last updated: 30 May 2026

Overview

The Copeland Islands lie three miles north of Donaghadee, rising from the Irish Sea as a trio of distinct landmasses: Great Copeland (Big Island), Lighthouse Island (Old Island), and Mew Island. Though uninhabited today, the archipelago has long served as a vital waypoint for mariners and a sanctuary for coastal wildlife. Designated an Area of Special Scientific Interest (ASSI), the islands sit within the civil parish of Bangor and are managed by the National Trust. They offer visitors a rare chance to step away from the mainland and experience Northern Ireland’s rugged maritime character, complete with historic stone towers, active navigation beacons, and one of the region’s most important seabird habitats.

Lighthouses & Maritime Heritage

Human activity on the islands dates back to the 18th century, when the first beacon was erected around 1715 to guide ships through the busy approaches to Strangford Lough. Early keepers burned through roughly 400 tons of coal annually to maintain the light. In 1813, a substantial stone lighthouse was built on Lighthouse Island, supporting a small community of around 100 people that included a schoolmaster and 28 pupils.

The original tower was eventually replaced in 1884 by the Mew Island Lighthouse, which remains an active, automated beacon guiding vessels to this day. The 1815 structure on Lighthouse Island was left to the elements, its weathered stone walls now standing as a striking reminder of the islands’ working past. In 1954, naturalist Arnold Benington transformed the former keeper’s cottage on Lighthouse Island into the Copeland Bird Observatory, shifting the islands’ focus from maritime navigation to scientific conservation.

Seabird Colonies & Wildlife

The Copeland Islands host internationally significant breeding populations, making them a premier destination for birdwatchers. The islands are particularly noted for:

  • Manx shearwaters – around 4,800 breeding pairs, representing over 1.7% of the global population.
  • Arctic terns – the largest colony in Ireland, with approximately 566 pairs.
  • Mediterranean gulls – where Northern Ireland’s first successful breeding pair was recorded.
  • Common eiders – roughly 140 pairs, alongside black guillemots, water rails, and stock doves.

Raptors such as hen harriers, peregrine falcons, and merlins patrol the skies during the summer months. Puffins and lesser black-backed gulls also join the breeding colonies. Beyond the birds, the surrounding reefs and rocky outcrops provide haul-out sites for grey and common seals, while harbour porpoises, bottlenose dolphins, and minke whales are occasionally spotted in the clearer waters.

Coastal Flora & Landscape

The islands’ plant life reflects their exposed maritime setting. Vegetation ranges from short, rabbit-grazed turf and rank bracken to pockets of salt-marsh and semi-improved wet grassland on Great Copeland. Botanical highlights include Scots lovage, which reaches its southernmost European limit here, and sea purslane, found at its northernmost Irish limit. Exposed rock faces support hardy species like English stonecrop and rock sea-spurrey. The marine environment is equally diverse, with 56 recorded algae species and 19 lichen species documented across the archipelago.

Getting There & Boat Trips

Access to the Copeland Islands is strictly by boat from Donaghadee harbour. There is no admission charge, and the islands are free to explore. During the summer months (typically May to September), a seasonal passenger ferry runs short, guided trips that provide a convenient way to experience the archipelago. Outside of ferry season, or for more flexible scheduling, private charters can be arranged year-round with local operators such as Nelsons Boats and The Brothers.

Parking is available at the Donaghadee harbour car park on a first-come, first-served basis. Boats typically drop visitors on Lighthouse Island or Great Copeland, depending on weather and tide conditions. It is advisable to check sea states before departure, as the Irish Sea can become rough quickly.

Walking & Hiking

Great Copeland features a well-marked circular walking route of approximately 5 km (3 miles). The trail winds along maritime cliffs, across salt-marsh edges, and through grassland interiors, offering uninterrupted views of the surrounding sea and the two smaller islands. The walk is graded as moderate and requires a reasonable level of fitness and sturdy footwear. While suitable for families with older children, the uneven terrain and exposed coastal sections mean it is best avoided in high winds or heavy rain.

Practical Tips for Visitors

  • Best time to visit: April to August offers the most active seabird colonies and reliable ferry schedules. Winter visits provide dramatic coastal scenery and better chances of spotting seals on the rocks.
  • What to bring: Binoculars are essential for birdwatching. Pack waterproof layers, a hat, and plenty of water, as there are no facilities on the islands.
  • Conservation guidelines: The islands are a protected ASSI. Visitors must stay on established paths, avoid disturbing nesting birds, and refrain from collecting plants or shells.
  • Dogs: To protect breeding wildlife, dogs should be kept on a short lead or left at home between April and August.
  • Booking ahead: The National Trust oversees the site, and large groups must coordinate visits in advance to minimise ecological impact.

Pair your island visit with a stop at Ballycopeland Windmill on the mainland, a restored 19th-century structure just a short drive from Donaghadee that provides useful historical context before you head out to sea. Always check local tide tables and weather forecasts before booking your boat trip, as access windows can shift quickly depending on sea conditions.
