The Titanic museum (in Belfast, NI) was an amazing experience. They did such a good job curating the museum and presenting it in a way that immersed the visitor to such an extent that I got emotional at several points.
Glendalough and the Wicklow Way were absolutely gorgeous. It was so peaceful to be in nature and see such a historic monastic town.
Kilkenny Castle was the first castle I had ever been too and not only was it pretty but so was the town of Kilkenny.
Howth was such an incredible hike and view right along the cliff side. I could not get over the view and the secret beach we went down to was beautiful.
