No St. Paddy’s Day in NYC would be complete without staking out a spot at this parade, which makes its march up Fifth Avenue. (The event is even older than the United States; it was started by a group of homesick Irish conscripts from the British army in 1762.) More than 2 million onlookers are expected to show up for the annual spectacle! Families can don their Irish beads, hats and shamrock stickers and watch as a sea of green-clad marchers displays Irish pride. Expect the sounds of bagpipes and marching bands, plus plenty of kilts. All ages.
