Overview & Name Origin
Carbery’s Hundred Isles form a striking archipelago along the south-west coast of Ireland, stretching across Long Island Bay and Roaringwater Bay in County Cork. The poetic name comes from Thomas Davis’s 1844 narrative poem The Sack of Baltimore, which romanticised the 1631 Algerian pirate raid on the nearby fishing village. The opening line, “The summer sun is falling soft on Carbery’s hundred isles”, cemented the phrase in popular imagination, even though the actual count sits around fifty landforms. These range from inhabited islands like Cape Clear Island, Sherkin and Long Island to bare limestone skerries that vanish at high tide. The Gulf Stream moderates the climate, allowing pockets of lush vegetation to thrive alongside stark, treeless cliffs and mixed shingle beaches. The eastern islands, sheltered by the Ilen River estuary, have historically been the most fertile and densely settled.
Island Highlights & What to See
Each island in the archipelago carries its own distinct character and history:
- Cape Clear (Oileán Chléire): Ireland’s southernmost inhabited island and the largest of the Hundred Isles. This active Gaeltacht community is home to a 5,000-year-old passage grave, 12th-century church ruins, a 14th-century castle, and the Cape Clear Heritage Centre. Summer brings Irish language immersion courses and the renowned Cape Clear Storytelling Festival.
- Sherkin (Inis Arcáin): The second-largest island and a former O’Driscoll stronghold. Highlights include the ruins of Dun na Long (Fort of the Ships) beside the pier, a 15th-century Franciscan friary, Slievemore Hill for panoramic views, and three sandy beaches including Silver Strand and Trá Bán.
- Long Island (Inis Fada): A slender, unspoiled island measuring nearly 5 km long but less than a kilometre wide. Once home to over 300 residents, it now hosts a small permanent community. The eastern end features Copper Point Beacon, a lighthouse marking the entrance to Schull Harbour, and remnants of 19th-century copper mining.
- Heir Island (Inis Uí Drisceoil): Known as the “Island of the O’Driscolls,” it offers a sailing school, seven sandy beaches, and a central reed-bed marshland supporting over 200 wildflower species. The Island Cottage restaurant hosts weekend cooking workshops focusing on local seafood and organic produce.
- The Skeams & Smaller Islets: East and West Skeam are grazing islands with unspoiled beaches, ruined farmhouses, and a modest campsite. Nearby islets like Goat Island, the Calf Islands, and Castle Island are primarily used for grazing and offer quiet wildlife viewing from boat tours.
Wildlife, Nature & Sea Swimming
The sheltered waters of Roaringwater Bay support a rich marine ecosystem. Seals, otters, dolphins and porpoises frequently visit the bays around Sherkin and Cape Clear, while summer whale-watching tours target minke, fin and humpback species. Cape Clear hosts a bird observatory, and the cliffs and grassy islets provide nesting grounds for gulls, cormorants and winter-migrating waders. Lough Hyne, a unique salt-water lake a few kilometres east of Baltimore, is a designated nature reserve popular for wild swimming, snorkelling and permit-required scuba diving.
For swimmers, Heir Island’s Reen strand offers a sandy beach framed by marshland, while Sherkin’s Silver Strand and Trá Bán are ideal for family dips. Cape Clear’s North Harbour provides calm, pebble-shingle waters, and the South Harbour caters to more confident swimmers. All spots are reachable on foot from ferry terminals.
Festivals & Cultural Events
The islands come alive with seasonal gatherings that showcase traditional music, sailing, craft and the Irish language:
- May: Baltimore Fiddle Fair and Wooden Boat Festival
- June: O’Driscoll Clan Gathering on Cape Clear
- July–August: Sherkin Family Regatta and Baltimore Regatta
- September: Cape Clear Storytelling Festival and Fastnet Race Memorial Exhibition
These events are family-friendly and often feature local artisans, traditional musicians and Gaelic-language workshops.

Practical Tips for Visitors
- Timetables & Weather: Check ferry schedules in advance; winter services are reduced and sudden weather changes can occasionally cause short delays.
- Bikes & Gear: Bicycles and kayaks are permitted on most ferries for a small fee (typically €2 per item). Book space ahead if possible.
- Pets & Connectivity: Dogs are welcome on ferries and most islands if kept on a lead. Mobile reception is patchy on smaller islands, so download offline maps and carry some cash.
- Clothing & Supplies: Pack layers and waterproof footwear. The Gulf Stream brings mild temperatures, but coastal winds and sudden showers are common. Smaller islands have limited or no shops, so bring water, snacks and a windproof jacket.
- Getting Around: On arrival at Cape Clear, an electric shuttle bus meets each ferry for a small charge, providing transport across the island. Advance booking is recommended.
- Diving: Lough Hyne and several offshore sites require permits for scuba diving. Local operators in Baltimore and Schull offer guided courses and equipment hire.
Plan your visit around the ferry timetables, allow extra time for parking in Baltimore or Schull during summer, and you’ll find a coastal network where history, wildlife and quiet island life are just a short boat ride away.
