This wild, rugged island located off the coast of County Antrim is the only inhabited island in Northern Ireland and contains an Iron Age fort, a number of standing stones, Robert the Bruce Castle, a tower house, a seal colony, and much more. 

In addition, it is one of 43 Special Areas of Conservation in Northern Ireland, being home to tens of thousands of seabirds, including puffins, razorbills, and more.

What also makes a visit to this island memorable are its impressive cliffs, standing at 230 feet (70 meters) that provide a home to all of those seabirds.

From there, you can see the Inishowen peninsula in Co. Donegal to the west, as well as the Mull of Kintyre in mainland Scotland, which is about 11 miles away.

Main Attractions on Rathlin Island

Bruce's Cave – while four caves in Ireland and Scotland bear the name, “Bruce’s Cave,” this one is said to be the location where Robert the Bruce met the spider after being defeated at the Battle of Strathfillan.

The story goes that while waiting out the winter of 1306, Robert watched a spider on the cave wall trying to spin its web.

You can only get to this by boat and when the conditions are calm.

Rathlin West Light Seabird Center – witness a thriving seabird colony, including thousands of puffins at this popular attraction that is part of Rathlin’s unusual upside-down lighthouse

Completed in 1919, the lighthouse lamp was placed at the bottom so that it could better penetrate the dense, low fog that frequently surrounds the island. Admission: £5 for adults, £2.50 for children. 

Rathlin Castle – built in the 13th century by John de Courcy, it subsequently passed into the possession of several families in the area. In 1575, English forces attacked the castle, which led to the island’s greatest tragedy, the Rathlin Island Massacre. It sits on top of a cliff, with views of Kintyre and Islay in Scotland on the horizon.

Walking Trails – there are numerous walks you can take on the island. They include the 4-mile circular Roonivoolin Walk, the 1.9-mile circular Keeble Cliff Walk, the 2.1-mile circular Kinramer North Walk, the 1.9-mile circular Kinramer Trail, the 4-mile linear Rathlin Trail, and the 1.8-mile circular Ballyconaghan Trail.

In the 6th century, a monastery was founded there by St. Colmcille. It dominated island life for several hundred years up until 1595 when it was plundered and destroyed by British troops in their war against local chieftains. 

The monastery’s bell tower still remains.

Some other historical events that are associated with the island include the Siege of Tory Island in 1608, which involved a number of rebels from the island who took siege in the island’s castle, only to be defeated by the Crown's forces. 

In October 1914, the British battleship, the HMS Audacious sank off the waters of Tory Island, a  fact that was kept secret until 3 days after the end of WWI.

The sinking was witnessed and photographed, however, by passengers on the White Star ship, the RMS Olympic, sister ship to the Titanic

Today, Tory Island is a haven for artists, photographers, and bird watchers. 

What makes it even more unusual is the fact that it is the only place in Ireland to have an elected king, who acts as a community spokesperson, welcoming visitors to the island.

The last king of Tory, Patsy Dan Rodgers, died in 2018.

Arranmore Island, Co. Donegal

In 2019, some of the islanders from Arranmore Island wrote open letters to residents in the United States and Australia asking them to move to their less crowded part of the planet.

The letters generated a lot of interest abroad and perhaps some readers took the call seriously and at least visited this beautiful island that is a mere three miles from the mainland and the town of Burtonport in Co. Donegal. 

The clear waters surrounding Arranmore Island mean that it is an ideal place for outdoor activities such as diving, sea angling, sailing, and kayaking.

Sea anglers are also attracted to the area, given the waters’ rich source of brown and rainbow trout. 

The island is the perfect place for walking and cycling. Both regular bikes and e-bikes are available. Rock climbing is also a popular activity on the island. 

But really, if all you want to do is kick back and enjoy the solitude, Arranmore Island is the perfect place to do so, while taking in the magnificent views as well.

Arranmore Lighthouse – the first lighthouse to be built in Co. Donegal in 1798. Its light was first powered by electricity in the 1970s.

Eire Sign 75 – situated on a hill along the coast, the Eire 75 sign was created to show Ireland’s neutrality during World War II and as a navigational aid for allied planes flying overhead. 

Walking Trails – the 14-km (8 miles) circular Sli Arann Mhor walking trail takes you around the island where you can enjoy the superb coastal scenery. There is also a spur walk to the lighthouse.

Tours – during the summer months, be sure to catch the Sea Safari and Marine Heritage Tours. Once you’re out on the open sea, you’ll have a bird's-eye view of the island’s sea cliffs and caves, its nearby sea stacks, and the Arranmore Lighthouse. Diving expeditions are also available, as well as seal watching trips and deep-sea angling excursions.

The pillars were constructed in the mid-1800s to line up with the Black Rock Lighthouse and as an aid for boats as they traveled across the bay at night. 

Coney Island got its name from the many rabbits that inhabit it. Its name in Gaelic means “Island of Rabbits.”

During the 1800s, the merchant ship “Arethusa” sailed regularly between Sligo and New York City. The captain of the ship, as he passed the island, noted the number of rabbits on Coney Island and then apparently gave New York’s Coney Island its now familiar name. 

If you choose to visit Coney Island on foot, be sure to check the tide times. A texting service is available during the summer months by texting the word Coney to 53600 (if you have an Irish phone) or 81400 for NI/UK mobile phones. 

In an emergency, dial 999 or 112 and ask for the coast guard service.

Portadoonthis is the only natural lagoon on any of Ireland’s offshore islands. Overlooking it are the remains of a 9th-century dun or fort. It was apparently used by Norsemen during raids of the island in their search for gold. This is an excellent spot for swimming and pier jumping at high tide. 

Walking Trails – there are two looped walks on Inishturk Island. They include the 5-km (3 miles) Lough Coolaknick Loop, which will take you about 1 to 1.5 hours, and the 8-km Mountain Common Loop along the island’s cliffs, which will take approximately 2 to 2.5-hours.   

Tours – experience the pristine waters off the coast of Inishturk Island and catch some fish while you’re at it, thanks to a private sea angling tour.  

Accommodation: If you’re looking to stay the night in this glorious place, here are the places you should consider: Ocean View House, Tránaun House, and the Radharc na Réalta, and Inis Toirc glamping sites.

How to Get to Inishturk Island

You can catch the ferry at Roonagh Pier in Louisburgh that will bring you to the island. O’Malley Ferries offers daily service to Inishturk.

Clare Island, Co. Mayo

For centuries Clare Island off the County Mayo coast has been known as a former stronghold of the O’Malley clan, the powerful seafaring family that ruled much of County Mayo. Through the Middle Ages, Clare Island was part of their landholdings.

The most famous member of the O’Malley family is undoubtedly Grace, otherwise known as Grainne Uaille or Granuaile.

The O’Malley tower house, also called Granuaile’s Castle, is located close to the pier in a strategically important location that enabled the pirate queen to control the waters of Clew Bay and the surrounding seas off the Mayo coast.

The island, which has been immortalized by the Irish band The Saw Doctors in their song, “The Green and Red of Mayo,” boasts the most dramatic cliffs in Europe and are home to large numbers of nesting seabirds.

Its flora and fauna have been studied in depth since the early 1900s, so if you’re a nature lover, this is the place to spend some time.

Clare Island Abbey – built in the 12th century, this Cistercian Abbey is reputedly the place where O’Malley is buried. What makes this abbey unique from many others like it in Ireland is the fact that medieval wall paintings still survive on its walls.

The paintings depict mythical, human, and animal figures. It is thought that they were commissioned by the O’Malley chieftains. Flash photography and touching the walls are not allowed.

Archaeological Remains – before the O’Malley’s came to Clare Island, there was a population of people long before them who lived off the land. A large number of Bronze Age mounds revealed the presence of farming tools such as stones and troughs.

The remains of a Megalithic tomb are also located on the island, dating from about 3,000 to 4,000 B.C. A guide to the island’s archaeological sites is available at the Clare Island Heritage Centre.

Clare Island Lighthouse – this is the only two-towered lighthouse in Ireland. It was built in 1806 by the Marquis of Sligo. It was decommissioned in 1965. It now serves as luxury accommodation.

The Napoleonic Tower – constructed in 1804, this tower is similar to the other watchtowers along Ireland's coastline. After Napoleon’s defeat at the Battle of Waterloo in 1815, most of the towers, including this one, were abandoned.
