The Aran Islands Loop Trails are official waymarked day walks on Inis Mór, Inis Meáin and Inis Oírr in Galway Bay, off Ireland’s west coast. Individual circuits range from roughly 5 km to 16 km; the representative 12 km route is Lúb an Chorrúch on Inis Mór. Expect easy to moderate walking on limestone lanes, green roads, sandy tracks and exposed clifftop. These loops suit hikers who want ferry-accessed island walking, prehistoric forts and Gaeltacht villages without committing to a continuous long-distance trail. See more routes in Ireland.
Route Overview
This is a network of self-contained loops, not a point-to-point thru-hike. Each circuit starts and finishes at the island pier or main village: Kilronan on Inis Mór, and the pier areas on Inis Meáin and Inis Oírr. Ferries run year-round from Rossaveal in Connemara and seasonally from Doolin in County Clare. The main Inis Mór options are Lúb Dún Eochla, Lúb an Chorrúch and Lúb Chill Mhuirbhigh; Inis Meáin has Lúb Dún Chonchúir; Inis Oírr has Lúb Ceathrú an Locha and Lúb Ceathrú an Phoillín. For other Irish island walking, compare the Inishbofin Loop Trails or Cape Clear Island Loop.
Aran Islands History and Landscape
The Aran Islands share the Burren’s glacio-karst limestone, with bare pavement, clints, grykes and dense drystone field walls shaping the walking. Rising post-Ice-Age seas separated the islands from the mainland about 10,000 years ago. The islands are also a Gaeltacht area, where Irish remains part of daily life. On Inis Mór, St Enda founded an early-Christian monastic settlement in the 5th century, and the loops pass or approach a landscape rich in prehistoric forts, stone churches and traditional field patterns.
Notable highlights
- Dún Aonghasa (Dun Aengus): A prehistoric stone fort on Inis Mór set on the edge of a sheer 100 m Atlantic cliff. Its concentric drystone walls and cheval de frise make it the major highlight of the 16 km Lúb Chill Mhuirbhigh loop.
- Dún Dúchathair (The Black Fort): A dramatic promontory fort south of Kilronan on Inis Mór. It is older and less visited than Dún Aonghasa, with exposed cliff-edge walking nearby.
- Poll na bPéist (The Worm Hole): A natural rectangular sea pool cut into the limestone shelf below the Inis Mór cliffs. It is well known as a Red Bull cliff-diving venue and is a distinctive coastal feature for walkers.
- Dún Eochla: A well-preserved circular drystone ring fort near the high point of Inis Mór, at roughly 100 m. It is the centrepiece of the 10 km Lúb Dún Eochla loop, with views towards Connemara and the Cliffs of Moher.
- Dún Chonchúir: A large oval stone fort on the high ground of Inis Meáin. It is the high point of the 5.2 km Lúb Dún Chonchúir and one of the best-preserved cashels in Ireland.
- The Plassey wreck and O’Brien’s Castle: On Inis Oírr, the rusting MV Plassey wreck is a landmark on the 7 km Lúb Ceathrú an Locha. O’Brien’s Castle is a ruined tower house on high ground with views across the island and Galway Bay.
Challenges to expect
The walking is low-level, but Atlantic exposure matters. Clifftop sections near Dún Aonghasa and the Black Fort are unfenced, and wind or poor visibility can make them serious. Surfaces are mostly firm, but limestone pavement, grassy edges and sandy tracks can be uneven. Navigation is helped by colour-coded posts and green arrows, but check the correct loop before leaving the pier. Ferry times are part of the logistics, especially outside summer.

A self-contained loop from Kilronan on Inis Mór. The main landmark is Dún Eochla, a circular drystone ring fort near the island’s high point.
The Inis Mór blue loop and the representative distance used for this listing. Expect quiet limestone-walled lanes, paved island roads and coastal island terrain.
The longer moderate Inis Mór loop, with Dún Aonghasa as its climax. Length and exposed clifftop ground make it more demanding than the shorter island loops.
An easy loop on Inis Meáin with 90 m of ascent. It reaches Dún Chonchúir, the large stone fort on the island’s high ground.
An easy loop on Inis Oírr with 90 m of ascent. The route includes the Plassey wreck, one of the island’s best-known landmarks.
A longer easy loop on Inis Oírr, starting and finishing at the island pier area and using the island’s quiet roads, tracks and limestone landscape.
