Overview
The Inishowen 100 (Irish: Inis Eoghain 100) is a 100‑mile (160 km) sign‑posted loop that hugs the rugged coastline of the Inishowen Peninsula, the northernmost tip of the Republic of Ireland. The route is part of the Wild Atlantic Way and is celebrated for its sweeping sea views, sandy bays and a string of historic sites that can be visited at a leisurely pace. Whether you drive, join a coach tour or take on the more demanding cycle version, the loop can be completed in a half‑day for a quick taste or stretched over a full day to linger at the many coffee stops, beaches and museums.
History & Background
Inishowen has been a crossroads of culture for millennia. The peninsula’s most iconic historic landmark, Grianán of Aileach, crowns Greenan Mountain and dates back to around 1700 BC, when the powerful Northern Uí Néill dynasty erected the stone fort. Later, during the Napoleonic era, Fort Dunree was built to protect Lough Swilly, and today it houses one of the world’s finest collections of coastal artillery. The Doagh Famine Village offers a poignant, guided glimpse into 19th‑century rural life, while the Glenevin Waterfall and Mamore Gap illustrate the natural forces that have shaped the landscape. The modern Inishowen 100 route was formalised to showcase these layers of heritage alongside the peninsula’s spectacular beaches.

Practical Information
The Inishowen 100 is free of charge and open year‑round. The official start point is sign‑posted at Bridgend (near Newtoncunningham), but the loop can be entered at any convenient location – many visitors begin at Grianán of Aileach or in the town of Buncrana. The minimum recommended time to enjoy the full circuit is 5 hours, though most travellers allocate a full day to allow for meals, museum visits and beach walks.
Getting There & Parking
- By car: The route follows the N13, R238 and a series of coastal roads. Large coach parking is available at designated Wild Atlantic Way discovery points; smaller cars can use the free lay‑bys at Bridgend, Dunree and Knockamany.
- By bus: Regular services run between Derry, Letterkenny and Buncrana; the Inishowen Visitor Centre in Buncrana can arrange local coach hires.
- By cycle: The cycle version is classified as “tough” – expect steep ascents at Mamore Gap and Glengesh Pass. A high level of fitness is required, and many cyclists break the loop into two‑day stages.
