Poolbeg Lighthouse Walk
A walk out to the Poolbeg Lighthouse along the Great South Wall offers one of Dublin's most unique coastal experiences. Stretching for over three miles into Dublin Bay, the wall is one of the longest sea walls in Europe, providing a flat and uninterrupted path that feels like a true walk on the water.
The walk starts from the car park at the western end of the Great South Wall at the mouth of the River Liffey. As you head out, you're immediately struck by the vastness of Dublin Bay. To your left, you have the industrial working port of Dublin with its large cargo ships and ferries, a constant reminder of the city's maritime heritage. To your right, the expansive Sandymount Strand stretches out, a massive tidal flat that reveals a different landscape depending on the tide. Beyond the strand, the coastline curves around towards Dun Laoghaire and Dalkey, with the majestic Dublin and Wicklow Mountains providing a stunning backdrop.
You can continue your walking by heading south to pick up the splendid Sandymount Beach Walk or north to explore the Bull Island Nature Reserve.

The walk's main attraction is the iconic Poolbeg Lighthouse. Built in the 18th century, with its current red-hued design added in the 19th century, its bold colour stands out against the sea. As you approach it, you get a close-up view of its elegant design and the powerful waves that crash against the wall.
Poolbeg Lighthouse. The entire journey is exposed to the elements, so it can be exhilarating on a windy day, but also offers a beautiful sense of peace and isolation. It's a popular spot for locals and visitors alike, providing a fantastic vantage point for watching birds, ships, and enjoying a sense of being out at sea while still being firmly connected to the city.
