I loved my stay at Luisin Cottage and the owners communicated very well. The cottage was very clean and comfortable. Carlingford is a lovely village - definitely not all Stag and Hens! For high quality meals, I'd recommend the Kingfisher Bistro and Bay Tree; the fresh-baked goods at the local shop are also a food highlight of the village.
Outside the village, there are plenty of options for walking sections of the Táin Way; a walk up Slieve Foye and Maeve's Gap are well worth it, or just along the Greenway towards Omeath and back through the woods
