A city by foot
Dublin is a great town for anybody who likes to walk. It's relatively small and all main attractions are in short distance from each other. The most striking thing about Dublin, in my opinion is the gothic architecture (for example Trinity college or the castle) and the lovely parks (Merrion square and St Stephen's Green) which I highly recommend to visit for a picnic or of that sort.
Insider Tip:Visit Howth! Take the train for about 30 min from the city. It's an amazing costal village!!
