Poolbeg Lighthouse most photographed spot in Dublin but barely any tourists go because requires proper 45-minute walk from Sandymount DART station. Worth every step.

Follow strand at low tide for easier walking. Gets windy on breakwater so bring layers. Views back to city with Poolbeg towers (red/white striped chimneys) stunning - classic Dublin shot without crowds.

Check tide times before going. High tide makes walk much harder, potentially dangerous. Distance about 3.5km each way along beach and breakwater.
