Dalkey Island (Gaelic: Deilginis) is an uninhabited rocky island less than 300 kilometers offshore from the village of Dalkey. Once inhabited, the island still boasts a number of archaeological remains, including ruined houses, an old church and the Martello tower. A friendly island that’s easy to visit!
Dalkey Island has the advantage of being just 5 minutes by boat from Coliemore and Bulloch ports, Dalkey’s local harbors. Open to visitors all year round, the island is home to numerous archeological remains dating back to prehistoric times, the Viking invasions and the Middle Ages. (Many of the objects found on the island are on display at the National Museum of Ireland in Dublin).
Among the things to see, we recommend a visit to St Begnet’s Church, a 9th-century church now in ruins. The latter is said to have been abandoned following the Viking invasions, when the Vikings decided to use Dalkey Island as a port base.
Not far from there, you’ll also find a superb Martello tower. Built in the early 1800s, it is believed to have been constructed by the British as a surveillance and defense post during the Napoleonic Wars. In remarkable condition, it is particularly recognizable, even from across the river in the village of Dalkey.
Beyond these archeological curiosities, Dalkey Island is a charming island, ideal for walking and fishing. You can set off with your rod, and try to catch coalfish or mackerel. The island is also home to a few protected seals: with a bit of luck, you might just catch a glimpse!
You can also reach the island by kayak: some of the island’s rocky outcrops are more accessible at low tide.
