Islands in County Cork

Most of this list sits at two ends of the county. Cork Harbour holds Spike Island, a 15-minute ferry from Cobh, where a star-shaped fortress served as the largest prison in the world in the famine years; the guided tour and the self-guided walk together fill about three and a half hours. Fota Island and Great Island are in the same harbour and need no boat at all: a bridge and the railway tie Great Island to the mainland, and Fota is a short train ride from the city.

The rest are west. Garnish Island in Glengarriff Harbour is a garden Harold Peto laid out on bare rock, sheltered and warm enough for tree ferns, with a ferry that usually detours past a seal colony. Bere Island lies off Castletownbere at the mouth of Bantry Bay, compact enough to walk or cycle in a day past Martello towers and the restored guns of Lonehort Battery. Whiddy is ten minutes from Bantry Pier, with 31 residents and one pub; Sherkin is ten minutes from Baltimore; Cape Clear is further out, 12 km offshore and still a working Gaeltacht.

Dursey is the outlier. The only way on is a six-seat cable car, and the walk once you land is a loop of roughly 14 km. Sailings thin out well outside summer, so the western islands are easiest between late spring and early autumn.

Where to start

  1. Spike Island – Cork Harbour's prison island Cork Harbour

  2. Garnish Island (Ilnacullin) Glengarriff

    Bare rock in Glengarriff Harbour turned into a Harold Peto garden, warm enough for tree ferns, with a ferry that usually passes a seal colony.

  3. Bantry Bay – deep harbour, islands Bantry

    A drowned river valley 35km long and one of the deepest harbours in Europe, with boats out to Whiddy, Bere and the Garinish gardens.

  4. Bere Island – a Treaty Port in Bantry Bay Castletownbere

    Wedge tombs, four Martello towers and a Victorian battery on a compact island at the mouth of Bantry Bay, made for walking and cycling.

    The most southerly inhabited place in Ireland, a Gaeltacht island of 110 people where seals, basking sharks and whales pass 12 km offshore.

Garnish Island (Ilnacullin)

Glengarriff, cork

John Annan Bryce bought a bare rock in Glengarriff Harbour in 1910 and hired architect-designer Harold Peto to turn it into a garden. A shelter-belt of pine and the Gulf Stream give the island a microclimate warm enough for New Zealand tree ferns and Chilean myrtle, reached by a 15-minute ferry that usually detours past a seal colony.

Cork Harbour – forts, islands and sailing

Cork, cork

Cork Harbour runs from the city quays out to the Atlantic, one of the largest natural harbours in the world. It was the last sight of Ireland for 2.5 million emigrants and the Titanic's final port of call. Today you can tour restored coastal forts, ferry out to Spike Island, cycle the Crosshaven greenway, or sail from the home of the world's oldest yacht club.

Dursey Island – Ireland’s Cable-Car Island

Beara Peninsula, cork

A six-seat cable car – Ireland’s only one over the sea – is the sole way onto Dursey, a near-empty island off the tip of the Beara Peninsula. Once across, a roughly 14 km loop of the Beara Way runs through bog and old stone walls to a Napoleonic signal tower, with gannets, dolphins and the odd whale offshore.

Lonehort Battery – Bere Island fort

Bere Island, cork

Lonehort Battery is the largest of the seven gun batteries on Bere Island, built by the British Admiralty between 1898 and 1902 to guard Berehaven Harbour and the Royal Navy's dreadnought anchorage. Its restored northern sector keeps a 9.2-inch Mark X gun and two 6-inch guns above a mile-long dry moat, open for guided tours at €10 on summer Wednesdays, Saturdays and Sundays.

Spike Island, reached by a 15-minute ferry from Cobh. Allow about three and a half hours on the island for the guided tour and the self-guided walk. Fota Island, also in Cork Harbour, is a short train ride from the city and its gardens are free.
How do you get to Dursey Island?
By cable car, a six-seat car and the only one in Ireland running over the sea, at the tip of the Beara Peninsula. There is no ferry. Once across, the main walk is a loop of roughly 14 km along the Beara Way.
Which Cork islands can you visit without a boat?
Fota Island and Great Island in Cork Harbour are both tied to the mainland by bridge and railway, and Cobh sits on Great Island. St Finbarr's Oratory at Gougane Barra stands on a small island in Lough Eiroe, reached by a short causeway from the car park.
Where do the West Cork island ferries leave from?
Baltimore for Sherkin, about ten minutes across; Bantry Pier for Whiddy, also around ten minutes; Castletownbere for Bere Island; and Glengarriff for Garnish, roughly 15 minutes. Cape Clear lies 12 km off the West Cork coast, the longest of the crossings.
When is the best time of year to go?
Late spring to early autumn, when sailings are most frequent and Garnish's planting is at its best. Cape Clear's storytelling festival has run each September since 1994, and Lonehort Battery on Bere Island opens for guided tours on summer Wednesdays, Saturdays and Sundays.
