Overview
Sherkin Island (Inis Arcáin, ‘island of the sea porpoise’) lies at the mouth of Roaringwater Bay, under 2 km off the fishing village of Baltimore in County Cork and a ten-minute ferry from the pier. It is about 5 km long by 2.5 km wide – small enough to walk end to end, big enough that around 110 people live here year-round: farmers, oyster growers, marine researchers and a long-settled community of artists. Dry-stone walls line lanes heavy with fuchsia, and three sheltered sandy beaches make it one of the gentler places to swim in West Cork.
If you have a single afternoon, this is the shape of it: the ferry over, the friary and Silver Strand, and a later boat back. The three headline sights – the Franciscan friary, the O’Driscoll castle and the lighthouse – are all free and out in the open.
History
The friary was founded in 1460 and, unusually for an Irish monastic house, rode out the worst of the Reformation: friars were still on the island until the last of them died in 1796. Just above the pier stand the ivy-clad ruins of Dún na Long, the O’Driscoll clan’s coastal seat from the mid-15th century – Sherkin was the family’s ancestral home. Both were scarred in a 1537 raid by Waterford men, retaliation in a running maritime feud that reached all the way down to West Cork. The Barrack Point lighthouse, out on the western tip, went up in 1835 and is looked after now by locals.
The island’s calendar keeps the heritage ticking over: the Sherkin Regatta and its rowing races run on the third weekend of July, and the Open Ear experimental music festival has been held near the start of summer every year since 2016.
Getting there and the ferry
The ferry runs year-round from Baltimore Harbour, every hour or two, and the crossing takes about ten minutes. The 2026 fares are €8 single or €15 return for adults, €4 single and €7 return for students with a card, and €2 single, €4 return for children aged 5 to 18. Bring cash – the ferry does not take cards. There is a free car park by the pier in Baltimore, and it fills fast in July and August, so come early on a summer weekend.
On the island a rural transport bus meets the ferry, and bikes can be hired over the summer if you’d rather roll than walk.
Walking and the beaches
Sherkin is small enough that the network of lanes gets you everywhere on foot; you don’t need marked trails to reach the beaches, the friary or the lighthouse. Silver Strand is the pick of the beaches – reckoned one of the best in Cork, and popular for swimming and barbecues – while grey seals haul out on the rocks at Cow Strand. Wear proper shoes for the grass and gravel, and keep an eye on the tide if you walk the low shore.
The arts
The island’s creative streak is more than atmosphere. A visual-arts degree runs here in partnership with Munster Technological University (formerly Cork Institute of Technology). The Island Crafts Centre, on the island near the pier, is open Easter to October, 10am to 6pm, selling pottery, knitwear and other local work. Seasonal guided walks take in open studio doors, and the Jolly Roger pub keeps up traditional music sessions through the season.
Wildlife
Grey seals rest on the rocks at Cow Strand, and bottlenose dolphins and the occasional porpoise work the bay – often visible from the shore. For more, sea safari trips run from Baltimore or Schull and turn up basking sharks and minke whales over the summer.

Practical tips
There is a shop and post office on the island, but stock is limited, so bring anything specific you’ll need. Mobile signal is patchy across Sherkin. And a word on ‘Ireland’s most accessible island’: it earns the name because the ferry is short and frequent, not because it’s easy going underfoot – beyond the pier the lanes and ruins are uneven, so it is not one for wheelchairs past the immediate approaches.
Check the seasonal ferry timetable a few days ahead, bring cash for the boat, and arrive early to get parked in Baltimore. Once you’re over, the ruins, a session and a sunset from the lighthouse all fit comfortably into one afternoon.
