Times of St. Patrick's Day Parade
March 14th to March 18th 2019
It is strongly advisable to be at the parade route before 10:00 on the day. The route gets crowded fast and the best spots will be gone well before noon. The Parade starts from the northern edge of Parnell Square, near the Hugh Lane Gallery, at 12:00 noon. It then winds its way slowly down O'Connell Street, past Trinity College at College Green and on to Dame Street before it finishes at St. Patrick's Cathedral. The entire parade lasts approximately two hours. Festivities spill over into Dublin's pubs after the parade has passed. On St. Patrick's Day, Dublin is at its most mellow from 14:00 to 18:00. By then you will have seen the best. After 18:00, the locals head for home or their local pub to end the day's festivities on a quiet note.
