Perched dramatically on the cliffs of Howth Head, Baily Lighthouse offers one of the most stunning coastal views in Dublin. While you can't go inside the lighthouse itself as it's private property, the real magic is in the journey along the cliff path to see it. You'll be rewarded with breathtaking panoramas of Dublin Bay and the rugged coastline. For the best views without a long trek, take a bus to the Howth Summit car park, from where it's a much shorter and more accessible walk to the main viewpoints.
