What to pack for a holiday in Dublin

For spring and summer, pack plenty of light jerseys, jeans, long sleeved shirts, T-shirts, skirts and shorts, as well as a hat and sunscreen. Breathable walking shoes and sandals are essential, and always carry a raincoat and a warm top in case cooler weather rolls in suddenly. Hiking boots are a must for those who want to explore the nearby countryside.

Autumn and winter clothing should be warm and waterproof, and layers are important. Pack some long skirts, leggings and dresses, warm jerseys and long sleeved tops, jeans and trousers as well as hats, gloves and scarves. Footwear should include closed toe shoes or trainers, and boots or sturdy shoes will definitely keep the toes dry. Finally, some events may require formal attire, so pack something smart for a night on the town.
