Overview
Inch Island (Irish: An Inse or Inis na nOsirí – “Island of the Oysters”) lies in the sheltered waters of Lough Swilly on the north‑west coast of County Donegal. The island covers roughly 13 sq km (5 sq mi) and rises to 222 m at Inch Top. Two narrow causeway embankments, built by the Londonderry & Lough Swilly Railway in the 1850s, link the island to the mainland, making it easily reachable for walkers, cyclists and birdwatchers.
History / Background
- Pre‑historic era – Near Carnaghan the stone remnants of a portal tomb hint at Neolithic activity on the island.
- 15th century – Sir Cahir O’Doherty erected Inch Castle in 1454 on the south‑west shore; the ruin still crowns a cliff overlooking the lake.
- Early 19th century – Inch Fort, a Napoleonic‑era defensive structure built in 1812, stands on the northern tip (now on private land and not open to the public).
- 19th century railway works – The railway’s two embankments created a brackish lagoon, now known as Inch Lough, and drained the surrounding levels into fertile polders.
- 20th century – A small Presbyterian kirk and a Catholic chapel (Our Lady of Lourdes, 1932) served the island’s modest community; the 2011 census recorded 448 residents.
- Conservation – The lagoon and surrounding marsh were designated a Special Protection Area (SPA) under the EU Birds Directive, recognising its international importance for wintering and migratory waterfowl.
What to See & Do
Birdwatching and the Wildfowl Reserve
The Inch Wildfowl Reserve centres on the brackish Inch Lough and its surrounding marsh, grassland and polders. Four purpose‑built hides give unobtrusive views of the winter roosts, where thousands of whooper swans, greylag geese and other species gather. An 8 km looped trail skirts the lagoon, suitable for walking, running or cycling, and is dotted with benches, picnic spots and interpretive signs.

Education & Family Activities
The reserve’s Woodland Education Area provides curriculum‑based learning tools for primary and post‑primary groups, making the island an excellent outdoor classroom.
