Krewe of BOO! New Orleans' Official Halloween Parade celebrates a weekend of festivities and has become a tradition for tens of thousands of people.​ Happening the weekend before Halloween weekend, Krewe of BOO! is more than just a parade. It's a weekend full of events starting Friday afternoon through late Saturday night.​ Friday's events begin with the Royal Luncheon to the Jazz Second Line through the French Quarter to an afternoon Happy Hour at Pat O'Brien's, ending with the Captain's Party Friday night.

Saturday starts with the early morning New Orleans Zombie Run through the Warehouse District. Paraders line up in the afternoon and the Krewe of BOO! Parade rolls at sundown with V.I.P. Viewing Parties hosted along the parade route. It all ends with a blowout costume bash at the post-parade afterparty, The Monster Mash.​
