Overview
There are wild wallabies on an island three miles off Dublin. Red-necked wallabies, descended from a group Dublin Zoo sent out in the 1950s, now around a hundred strong, grazing the slopes beside the cattle. That’s the hook, but Lambay is more than a novelty: a square mile of volcanic rock rising to 127 m at Knockbane, with a Lutyens castle, tiered rose gardens and one of Ireland’s biggest seabird colonies. The catch is access. The island is privately owned by the Baring family’s Revelstoke Trust, private boats can’t land, and the only way on is a pre-arranged tour. If you book one thing, make it the guided nature walk with Eamonn McGrattan – three to four hours, capped at seven people.
History & architecture
Human activity on Lambay goes back to the Neolithic, when the island’s andesite – locally called Lambay porphyry – was quarried for stone axes. The name itself is Old Norse, ‘lamb island’. Early monastic settlement gave way to Viking activity and medieval ownership: in 1181 Prince John granted the island to the Archbishops of Dublin, and it later passed to Christ Church Cathedral. In 1560 the Dublin mayor John Challoner received Lambay and built a fort against smugglers. The Talbot family of Malahide held it in the 19th century, running a hunting estate, introducing deer and building a small school in 1834.
The island’s transformation came in 1904, when Cecil Baring bought it and commissioned Sir Edwin Lutyens to remodel the medieval fort into an Arts and Crafts castle. Lutyens also designed the White House, the harbour approach and the island’s only real-tennis court, and Gertrude Jekyll laid out the tiered rose gardens that still frame the castle’s sea views. The nature walk also passes the site of the 1854 wreck of the emigrant clipper RMS Tayleur, lost off Lambay with heavy loss of life.
Wildlife & nature
Designated both a Special Protection Area and a Special Area of Conservation under the EU Natura 2000 network, Lambay packs a lot of life into a small space. The andesite cliffs are nesting grounds for over 50,000 common guillemots, several thousand kittiwakes and razorbills, and smaller numbers of puffins, Manx shearwaters and greylag geese. Grey seals pup on the sheltered northern beaches.
The island’s most unexpected residents are the red-necked wallabies. Dublin Zoo sent a handful over in the 1950s, and the population has since grown to somewhere between 100 and 150. They’ve adapted to the Irish climate with thicker winter coats and now forage alongside the island’s cattle. The volcanic soil and a microclimate 1–2 °C warmer than the mainland support rare butterflies, native bees and a strong spring show of wildflowers.
Key seabird species include:
- Fulmar
- Cormorant & Shag
- Lesser Black-backed & Herring Gulls
- Kittiwake, Guillemot & Razorbill
- Atlantic Puffin
Activities & experiences
Access to Lambay is carefully managed to protect its ecology, but several structured experiences let you explore it responsibly:
- Castle & gardens tour – Walk the curtain-wall rampart, see the vaulted stone chambers and the 19th-century Catholic chapel with its Doric columns, and Jekyll’s rose gardens laid out to catch the coastal light.
- Guided coastal walks – Led by local guide Eamonn McGrattan, these tide-dependent trips include the boat over from Malahide or Howth and last three to four hours. Groups are capped at seven to limit the impact. The route covers historic structures, coastal geology and the best birdwatching vantage points.
- Whiskey masterclass – The Lambay Irish Whiskey Company runs private tastings in the Bothy Clubhouse, followed by a visit to the Sea Cask Room, where casks mature in the former lifeboat cottage and the salt-laden air works on the flavour.
- Real tennis – Built in 1922, the court is one of only two in Ireland, and is mostly reserved for guests staying on the island.
- Coastal trails – Eight named bays, including Talbot’s Bay, Saltpan Bay and Freshwater Bay, mix sandy stretches and rocky coves. The western harbour is the main landing point.
- Farm visits – The working estate raises Galloway cattle, Lleyn sheep and fallow deer.
Getting there & practical information
Lambay is a private island, and every visit must be arranged in advance – there is no public ferry, and private vessels can’t land. Boat transfers are organised by Lambay (or through Skerries Sea Tours) as part of the tour package, from Malahide or Howth, with crossings of roughly 25 to 40 minutes depending on the tide.
Paid parking is available at Malahide Marina through the PARKPNP app; note there are no public toilets at the marina, so plan accordingly before you set off. Tours run in the warmer months, roughly April to September, with spring and early summer best for nesting seabirds and pollinators; the island is closed to visitors over winter. Accommodation is limited to a historic harbour cottage and the Lutyens-designed White House, both off-grid on solar and wind power.

Nearby points of interest
Lambay sits opposite the coastal villages of Portrane and Rush, a natural extension of a north Dublin itinerary. A short drive inland leads to Ardgillan Castle, whose towerhouse and formal gardens make a complementary historic day out. Further north, Balbriggan has a working harbour, traditional pubs and a long beach. Book well ahead – tours are small and seasonal – and leave slack around the tide, since the crossing time shifts with it.
