Krewe of Boo, New Orleans official Halloween parade will march through Downtown New Orleans and the French Quarter on Saturday, October 22 at 6:30pm. The Krewe of Boo started in 2007 and while there were a couple of years that they didn’t parade, this year is looking like it’ll be a top-notch event that you don’t want to miss. There will be world class floats designed and built by Kern Studios, the best marching bands from the city, and a number of special marching units.
