There are plenty of things to do on the Aran Islands, regardless of which one you decide to visit.

Whether you’re clutching your hat against a howling gale at Dún Aonghasa or finding quiet moments of reflection at Synge’s Chair, the islands promise an unforgettable experience.

This guide uncovers the magic of Inis Mór, Inis Meáin, and Inis Oírr (read my guide on which Aran Island to visit if you’re still undecided).

Things to do on the Aran Islands

The map above will give you a quick sense of what to do on the Aran Islands – these are the main attractions.

Below, you’ll find the places on each island that I have enjoyed visiting the most. Cheers!

1. Dún Aonghasa

Dún Aonghasa is the most popular of the many places to visit on the Aran Islands.

This fort sits atop 300-foot cliffs on Inis Mór and is thought to date back as far as 1100 BC, with evidence of earlier settlement from 1500 BC.

Built by the Builg during the Bronze or Iron Age, it once featured four concentric dry stone walls, rising far above ancient sea levels.

Archaeological digs uncovered burial remains, tools, and defensive stones, emphasizing its historical importance.

As a filming location for The Banshees of Inisherin, this iconic site combines history, legend, and sweeping coastal views accessible via a 1km trail.

2. Dún Chonchúir

Dún Conor, located at the heart of Inis Meáin, is a beautifully preserved stone fort offering a window into Ireland’s ancient past.

Constructed during the first millennium AD, it features towering walls up to 6 meters thick, along with four terraces showcasing remarkable craftsmanship.

Unlike coastal forts eroded by the sea, Dún Conor has remained largely intact due to its central location.

Its mythical name, tied to Conor, brother of Aengus, adds a layer of intrigue to its history.

3. An Trá

Among the many mighty beaches in Galway, the pristine beach near the pier on Inis Oírr truly stands out.

Celebrated for its clear waters and eco-credentials, the beach has received both Blue Flag and Green Coast awards, a rare double accolade in Ireland.

Nestled beneath the ruins of O’Brien’s Castle, it offers breathtaking views across Galway Bay, the Burren, and Connemara.

4. Teampall Caomhán

Saint Caomhán, the protector of Inis Oírr, is remembered through the island’s 10th-century church, Teampall Chaomháin.

Once nearly buried by drifting sands, the church was uncovered and preserved by the islanders, revealing medieval features like its chancel arch and south-facing doorway.

Nearby, you’ll find Leaba Chaomháin, the saint’s grave, which was once believed to have healing powers.

5. The Wormhole

Another of the more popular things to do on the Aran Islands is to visit the Wormhole

This is a fascinating natural tidal pool on Inis Mór, located near Gort na gCapall.

Formed by underground ocean channels, this rectangular pool fills dramatically during high tide, creating a captivating spectacle.

Though it appears carved, the pool is entirely natural and steeped in folklore as a serpent’s lair. It gained international attention during the 2017 Red Bull Cliff Diving World Series.

6. Dún Eochla

Hidden at one of Inis Mór’s highest points, the 7th-century stone fort of Dún Eochla is a site many overlook.

Its elevated location offers stunning views of Connemara on clear days, while its two concentric circular walls provide insight into life in early Ireland.

Originally a chieftain’s stronghold, its thick inner walls, standing up to 5 meters high, were built to protect livestock and defend against rivals.

7. O’Brien’s Castle

Few castles in Ireland can match the striking location of O’Brien’s Castle on Inis Oírr.

One of the lesser-known castles in Galway, it a fascinating history.

Built around 1400 by the Clann Teige branch of the O’Brien family, it replaced an ancient ring fort, Dún Formna, which had stood on the ridge for centuries.

The castle’s past includes its capture by the O’Flahertys in 1582 and significant damage during Cromwell’s campaign in 1652.

8. Island pubs

One of my favourite pre-ferry-back-to-the-mainland things to do on the Aran Islands is to enjoy a well-earned pint.

Luckily, there are some wonderful island pubs.

My favourites are:

• On Inis Oírr: Tigh Ned (pictured above)
• On Inis Mór: The Bar
• On Inis Meáin: Teach Ósta (there’s only the one!)

9. The MV Plassey Shipwreck

The Plassey shipwreck is one of the most nostalgic Inis Oírr attractions, instantly recognisable from the opening credits of Father Ted, a classic Irish TV show.

In 1960, the cargo vessel struck a rock off the island’s coast and was washed ashore during a fierce storm.

Built in 1940 as HMS Juliet, it later served as a cargo ship, transporting goods like Irish whiskey, stained glass, and yarn.

The heroic efforts of islanders, using a breeches buoy, saved the entire crew, a feat commemorated in Ireland’s National Maritime Museum.

10. Inis Oírr Lighthouse

A trip to Inis Oírr Lighthouse is a must for those visiting the island.

Built in 1857, this striking black-and-white tower marks the southern entrance to Galway Bay.

It originally housed a first-order Fresnel lens capable of casting light 20 nautical miles across the Atlantic.

Over the years, it transitioned from paraffin to solar-powered lighting and was fully automated in 1978.

11. Cill Ghobnait

St. Gobnait’s Church is a medieval treasure on Inis Oírr, tracing its origins back to the 6th century when Saint Gobnait fled to the island to escape a family feud.

According to legend, an angel guided her to leave the island and settle on the mainland, where she founded a community in Ballyvourney, marked by the sighting of nine white deer.

The existing stone church, built in the 11th or 12th century, features a simple yet striking rectangular design made of limestone, with the remains of her beehive hut nearby.

12. The Big Lake

Loch Mór, the only freshwater lake on Inis Oírr, offers a serene break from the island’s rugged limestone landscapes.

Found along the route to the Plassey Shipwreck, the lake is a peaceful contrast to its rocky surroundings, with sparse greenery hinting at a time when woodlands once covered the island.

Today, it’s a tranquil spot that adds another layer to Inis Oírr’s natural beauty and historical narrative.

13. Visit Seal Colony Viewpoint

If you’re looking for unique things to do on the Aran Islands, Inis Mór’s Seal Colony Viewpoint is a great option!

The shores of Inis Mór are home to several seals, and they are a delightful sight to see as they bask on the rocks.

The official viewpoint at Portmurvy Beach is a fantastic picnic spot and one of the best places to observe these incredible creatures in their natural habitat.

14. Drop by Teampall Bheanáin

Perched high above Kilronan on Inishmore, Teampall Bheanáin is an 11th-century oratory believed to be the tomb-shrine of Benen, a follower of St. Patrick.

The structure’s walls, crafted from expertly fitted stone slabs, include a narrow north-facing doorway and a small east window overlooking the mainland.

Its unusual squared gables create a striking silhouette, and the altar intriguingly faces south—a mystery that continues to puzzle historians.

15. Eeragh Lighthouse Viewpoint

Eeragh Lighthouse, built in 1857 on Rock Island, marks the northwest entrance to Galway Bay.

Designed by George Halpin Jr., the lighthouse originally featured white and red bands, which were later updated to black.

This 31-meter structure transitioned to solar power in 2006, with its light flashing every 15 seconds and visible up to 18 nautical miles.

The viewpoint (here) offers fantastic views, though it’s much farther away than it may appear in photos.

16. See the Seven Churches

Despite its name, Na Seacht dTeampaill (the Seven Churches) includes only two churches, with surrounding structures believed to have housed medieval pilgrims.

This major pilgrimage site received a plenary indulgence from Pope Paul V in 1607.

Its focal point, Teampall Bhreacáin, was built between the 10th and 13th centuries and features notable masonry and a west wall added in the 13th century.

Graves of saints, including Leaba Bhreacáin with its inscribed slab, can also be found here, alongside fragments of a 4-meter-high cross.

17. Soak up more history at the Black Fort

One of the more overlooked things to do on the Aran Islands is to visit Dún Dúchathair (the Black Fort).

It’s very often overshadowed by Inis Mór’s more famous fort, Dun Aonghasa.

Though its exact age is uncertain, its dramatic clifftop location provides a breathtaking backdrop for a quieter, more isolated experience compared to Dún Aonghasa.

The fort’s ruins offer sweeping ocean views, with some describing the setting as the very edge of Ireland.

18. Island eats

There are some great places to eat on the Aran Islands, but few are as visually fantastic as Inis Mor’s Teach Nan Phaidi.

Set in a charming flower-adorned thatched cottage, is a must-visit for food lovers.

Inside, you’ll find a warm and cozy atmosphere with a menu featuring homemade dishes that blend traditional Irish recipes with modern flair.

19. Synge’s Chair

If you’re wondering what to do on the Aran Islands that’ll take you away from the crowds, take note!

One of the most peaceful places on Inis Meáin is Synge’s Chair, a clifftop viewpoint offering stunning views of the Atlantic.

Named after the famed poet and playwright, this tranquil spot is perfect for reflection and soaking in the wild beauty of the island’s dramatic coastline.
