Sailing the West Cork Islands: Sherkin, Clear Island and Heir Island — an Archipelago Unlike Anywhere Else in Ireland

Roaringwater Bay: Where Ireland's Island Life Is Most Alive

Spread across the sheltered waters of Roaringwater Bay in south-west County Cork, a loose archipelago of islands sits between the mainland shore and the full force of the Atlantic — accessible by small ferry, by charter yacht, by kayak, or by the kind of local boat that hasn't changed much in style or purpose in a hundred years. They are not particularly dramatic in the way of the Blaskets or the Aran Islands, which announce themselves from a distance and demand to be taken seriously. The West Cork islands tend instead to creep up on you: small, quiet, deeply inhabited by the kind of life that only small islands produce, and unexpectedly difficult to leave once you have arrived.

Among them, Sherkin Island, Cape Clear Island and Heir Island form a trio that between them cover almost every dimension of what Irish island life has to offer — art, sailing, wildlife, Gaelic culture and the particular silence that only comes when the last ferry back has gone and you are, briefly, on your own. The waters they sit in — Roaringwater Bay, Carbery's Hundred Isles, the channels between the peninsulas — are consistently regarded by experienced sailors as some of the finest cruising grounds in Ireland. Sheltered from the worst Atlantic weather by the Mizen and Sheep's Head peninsulas to the south and west, but open enough to catch the reliable south-westerly breeze that blows across the bay in summer, they offer a combination of protected anchorages, clear water and extraordinary scenery that is genuinely difficult to find anywhere else on the Irish coast.

Sherkin Island: The Island of the Arts

Sherkin Island is the closest of the three to the mainland — a ten-minute ferry crossing from Baltimore harbour. At five kilometres long by three kilometres wide, it is small enough to walk across in an afternoon and large enough to feel like its own world. The island has built a particular reputation as an island of artists: Sherkin has its own Visual Arts Degree Programme, and the work of its resident artists is sold at the Island Crafts Centre in Baltimore and exhibited throughout the summer in the ruins of a 15th-century Franciscan Abbey that has become one of the island's most distinctive landmarks.

Beyond the friary ruins, Sherkin offers four sandy beaches — all of them looking west to Cape Clear and the open Atlantic — three way-marked family-friendly walking trails, and a marine research station that has been recording the island's extraordinarily diverse fauna for decades. Sherkin sits within the Roaringwater Bay Special Area of Conservation and has been documented to support over 450 species of flora and fauna. The social centrepiece of Sherkin's summer is the Sherkin Regatta, typically held on the third weekend of July, when the island fills with sea rowers and their supporters and the small pier area transforms into something considerably more animated than its usual quiet self.

Cape Clear Island: Ireland's Southernmost Inhabited Island

Cape Clear — Oileán Chléire in Irish — sits three miles south of Baltimore harbour. Its 45-minute ferry crossing from Baltimore gives you time to watch the mainland recede and the Atlantic open up around you. It is Ireland's southernmost inhabited island, a Gaeltacht community where Irish is the everyday language, with a resident population of around 150 people. Cape Clear is home to Ireland's only manned bird observatory, which has been maintaining a daily species log since 1959. The island's location at the far south-western tip of Ireland makes it a natural landfall for migratory birds crossing the Atlantic, and the observatory regularly records rare and unusual species that draw birdwatchers from across the country.

Cape Clear offers a network of steep island roads and walking trails with views that on clear days extend to the Fastnet Rock lighthouse three miles to the south-west — Ireland's most southerly lighthouse and the turning mark of the biennial Fastnet Race, one of offshore sailing's most celebrated events. Saint Ciarán, the island's patron saint and allegedly one of Ireland's four pre-Patrician saints, was born on Cape Clear, and his holy well is one of the first features you encounter on arrival. Ferries to Cape Clear sail year-round from Baltimore, and seasonally from Schull.

Heir Island: Seven Sandy Beaches and the Sound of a Different Pace

Heir Island — Inis Uí Drisceoil in Irish — is 2.5 kilometres long and 1.5 kilometres wide, with a year-round population of around 25 to 30 people. The main access is via a small ferry departing from Cunnamore Pier six times a day during summer. The island has 23 beaches, over 200 species of wildflower, and a sailing heritage that runs deep — the Heir Island Sailing School is an Irish Sailing Association-approved training centre offering courses for mixed abilities of up to 25 sailors at a time. For those who simply want to be on the water without the instruction, the island's sheltered anchorages and accessible waters make it a natural stop for yachts cruising the bay.

Beyond sailing, the island supports an art gallery, a yoga and meditation retreat centre, and PizzHeiria — an artisan wood-fired pizza restaurant with a garden patio overlooking Roaringwater Bay, open Thursday to Monday from 2pm in summer, booking required. It has built a disproportionate reputation for its quality in a setting where open water views and the smell of burning pine make it one of the more memorable places to eat in the south of Ireland.

Why Roaringwater Bay Deserves More Attention Than It Gets

Baltimore harbour, the main departure point for all three islands, is a large, well-sheltered natural harbour hosting charter yacht companies, sailing clubs and experienced skippers offering day charters to the islands and beyond — out to the Fastnet Rock and along the coast to Castletownshend, Schull and Crookhaven. Weekend sailing from Baltimore can reach Bantry, Glengarriff and Bere Island. With a week aboard there is the possibility of cruising as far as the Skellig Islands off the Kerry coast. For a non-sailor, the three islands accessible by ferry from Baltimore make for a genuinely rewarding multi-day itinerary — each island different, each worth its own time.

The Bottom Line: Sherkin, Cape Clear and Heir Island are not the islands that usually appear in the opening paragraphs of pieces about Ireland's island heritage — that space tends to be occupied by the Arans or the Blaskets. But for anyone who makes the journey to Roaringwater Bay and crosses the water to even one of these three islands, the experience lands with a quiet insistence that takes a while to shake. This is Irish island life at its most alive, most accessible and most genuinely worth the effort of getting there.
