There Were An Estimated 400,000 To 500,000 Festivalgoers
Woodstock organizers expected roughly fifty thousand attendees but between four hundred thousand and five hundred thousand showed up. However, in secret, they did plan on two hundred thousand because they had pre-sold more than one hundred and eighty thousand tickets, but it still ended up being twice that much.
The festival gained more coverage as the promoters went from town to town asking if the festival could be held there but were repeatedly denied permission.
