Ireland's Eye: The Complete Island Guide

What Is Ireland's Eye and Why You Should Go

Ireland's Eye is a small, uninhabited island about a kilometre off Howth Harbour. There's no cafe, no toilet, and no mobile signal to speak of. It's genuinely worth the trip if you're into wildlife, history, or just want to stand somewhere that's been there since long before Dublin was anything like it is now.

The island is a Special Protection Area for birds, which means the seabirds have priority here, not tourists. That's the entire appeal. You're not going for a day lounging on a beach; you're going to watch puffins, gannets, and guillemots doing their thing, explore ruins that go back to the 8th century, and see Dublin from a distance that makes it seem almost manageable.

Getting There: The Ferry from Howth

The ferry departs from the West Pier in Howth Harbour. Two main operators run the service: Howth Ferries and Island Ferries, both working from the same spot on the West Pier where the trawlers are tied up. The journey out takes roughly 15 minutes. A guided tour is about 50 minutes on the water with commentary from someone who actually knows the island. Cost is roughly 25 euro for adults and 15 euro for children, but prices shift every year, so check before you go.

In summer, boats run roughly every hour starting around 10:30am. Shoulder seasons (April, May, September, October) are less frequent. Winter is quieter still, and bad weather can cancel sailings entirely. Ring ahead or check the operators' websites, especially in April or May when puffin season is starting but the weather is still unpredictable.

You can either do the guided tour (same boat back) or get dropped off on the island and picked up on a later sailing. The drop-off option only works if the weather is settled enough. It's excellent if you want a few hours to properly explore, but you're at the mercy of the tides and the forecast.

What You'll See: Wildlife and Birds

The headline attraction is puffins. They nest on the island from April through July, and if you time it right, you'll see them coming and going from their burrows. Puffins look ridiculous in person: smaller than you'd think, very round, and they fly like they're not entirely sure it's going to work. They'll absolutely arrest your attention.

Guillemots, razorbills, and cormorants are there year-round. Gannets are stunning: bright white with black wingtips, diving like arrows into the sea. You'll also see seals on the rocks, particularly grey seals, entirely unbothered by humans and watching you back with an expression of pure indifference.

The best window for puffins is April to July. June and July are safest for weather, though April and May are quieter and feel more special. By August, the puffins are gone back out to sea. The other birds stick around year-round.

The History: Church Ruins and a Martello Tower

St Nessan's Church is an 8th-century ruin in the middle of the island: stone walls, no roof, no drama. But it's old enough that you're standing in a building that predates almost everything in Dublin by hundreds of years. St Nessan founded a monastery here, and the island was a place of early Christian settlement long before Howth was properly established.

The Martello tower was built during the Napoleonic Wars, when Britain was worried that France might turn up in Dublin Bay with a fleet of warships. Squat, round, sitting on the highest part of the island, it's the kind of structure that says a lot about 1809 Ireland: practical, military, and a bit paranoid. You can see it from mainland Howth on a clear day.

The island has a true-crime footnote too. In 1852, William Burke Kirwan was convicted of murdering his wife here. She drowned; he said it was an accident. The Victorian court wasn't convinced. It was one of the biggest murder trials of the era in Dublin, and the ruins here have carried a slightly gothic edge ever since.

What to Do If You're Dropped Off

If you've got a few hours on the island, you can swim, explore the ruins at your own pace, do serious birdwatching, or just sit by the rocks with a packed lunch and watch Dublin shimmer in the distance. Swimming is possible in summer, though the water is cold. Exploring the church and tower takes about an hour. After that, you're there for the birds, the seals, and the view back towards Howth. Bring binoculars if you're serious about birdwatching.

What to Bring

There are zero facilities on the island: no toilets, no cafe, no water tap, no shelter. Bring water (more than you think you'll need), food if you're staying for a few hours, and pack everything out. Bring layers; the wind on the island is stronger than on the mainland even in June. Something waterproof is sensible. Bring sunscreen too: the sea reflects UV and you'll burn faster than you expect.

Best Time to Visit

April to July for puffins. June and July are safest for weather. May is quieter and might feel more special, but the weather can be moody. Summer, from late June through August, is peak season: more boats, more stable weather, busier crowds. Shoulder seasons offer better light and fewer people. Winter is possible if you're serious about seabirds and don't care about comfort.

The View Back

Here's the thing that sticks with you: standing on the island, looking back at Howth, you realise how close it actually is. A 15-minute boat ride, but from the island it looks like you could almost swim it. The cliffs are sharp and close. The harbour is real. The town is a thing you can see clearly, with all its chaos and its streets and its boats and its people doing ordinary Howth things. That's worth the trip alone. Everything else, the puffins and the ruins and the history, is gravy.
