Set out for a two-day exploration of Northern Ireland from Dublin. Visit the Celtic ruins of Monasterboice and enjoy Belfast's incredible Titanic Experience, an interactive walk-through telling the story of the ill-fated ocean liner. Spend free time exploring the streets and sights of the lively capital, including places like the renowned Crown Liquor Saloon and the Grand Opera House. The following day see sights recognizable from the HBO series 'Game of Thrones,' then depart for The Giant's Causeway, thousands of interlocking basalt columns that are Northern Ireland's only UNESCO-listed site.
