Overview
Island Roy (Irish: Oileán Ruaidh) sits in the tranquil waters of Mulroy Bay, about three and a half miles from the mainland villages of Downings and Carrigart in north‑west Donegal. Covering roughly 90 acres (≈ 36 ha) – some guides list the island as 65 ha – the low‑lying, gravel‑based terrain is a patchwork of green fields, rocky shores and seaweed‑lined beaches. In winter the vegetation turns a vivid rusty colour, giving the island its name – Ruaidh meaning “red”. From its highest points you can see the sweeping sand‑dunes of Rossapenna, the jagged Fanad Mountains and the rolling Donegal hills beyond.
The island is a designated Discovery Point on the Wild Atlantic Way, offering a quiet counterpoint to the more visited coastal attractions. Its small permanent population of about 26 lives primarily from farming, shellfish‑rearing and a modest tourism sector that has benefited from recent infrastructure upgrades.
History
The island’s official Irish name, Oileán na Bhráighe, translates as “island of the prisoners”. Historical links with nearby Doe Castle on Rossapenna suggest the island may once have housed captives associated with the castle’s 16th‑century occupants. Continuous habitation stretches back several hundred, possibly thousands, of years, and many current residents can trace their lineage to those early families.
In the early 19th century, Lord Leitrim attempted to evict the tenants and convert the pastures to cattle grazing. A determined female tenant, holding a 99‑year lease, successfully resisted, ensuring the community’s survival. The English name “Island Roy” was later coined by surveyors as a phonetic rendering of the Irish.
A tidal causeway linking the mainland at Rannach to the islet of Carraig an Ghóilín and then onto Island Roy was built in 1927. Before the causeway, children crossed the water on stilts to reach the island school at low tide. The causeway remains passable only at low tide; high tide submerges it.
A quirky scientific footnote: in 2010 NASA’s Opportunity rover named a small iron‑nickel meteorite on Mars Oileán Ruaidh, after this island, because of its reddish hue. The island is sometimes described as being “twinned” with the Red Planet.
What to See & Do
Walking and Beachcombing
The island’s unspoilt landscape makes it ideal for leisurely walks. Gravel paths wind through fields and along the shoreline, offering uninterrupted views of the Rossapenna sand‑dunes, the Mulroy coastline and the distant Fanad Mountains. Children especially enjoy the freedom of space, while adults can pause at natural viewpoints to absorb the sea‑air serenity.
Birdwatching
Rocky shores and grassy meadows provide nesting sites for a variety of seabirds. Visitors often spot gulls, terns and occasional waders. The island’s relative isolation means bird activity is less disturbed than on more frequented sites, making it a rewarding spot for keen birdwatchers.
Seaweed Baths
Abundant seaweed grows along the low‑lying beaches. Locals harvest it for traditional seaweed baths, reputed for their soothing properties. While there is no formal spa, adventurous visitors can collect a handful of fresh seaweed and enjoy a DIY soak on the beach.
Cultural Insight
A short stroll through the village reveals modest cottages and the small information point near the causeway entrance, where visitors can learn more about the island’s heritage and recent community projects.
Accommodation
For those wishing to extend their stay, Doherty Farm Holiday Homes offers three self‑catering cottages on the waterfront. Each cottage sleeps up to seven guests and includes modern comforts such as an infra‑red sauna, sea‑view bedrooms and a conservatory.
