Holidays in Ireland in February begin with St. Brigitte's Day, which falls on the first day of the month. This saint is very revered in Ireland, and therefore this day is celebrated with almost the same magnitude as St. Patrick's Day. So it makes sense to take tours to Ireland in February at the very beginning of the month to visit this colorful celebration.
During a vacation in Ireland in winter it is worth going on excursions to the castles of the country and its ancient cities. With dry and cool February weather is wonderful to wander the streets of Dublin and other cities of Ireland. Prices for a vacation in Ireland in February by Irish standards are low, so you can afford to visit more interesting places and actively visit pubs and restaurants.
