Beside all the great musical performances, organizers say there's a little something for everyone. You can get into the Foodfort and Alefort tastes without having a wristband as long as you're 21.
Local chefs make a special food just for Treefort Music Fest.
And if you're looking for something for the kids, there's Kidfort which includes activities like performances and crafts.
There's even an app where you can make your own schedule, share it with your friends, listen to artists and more.
"On Hackfort's part we have, an augmented mixed reality experience so, if you find any of the designated banners, click mixed reality on your phone and then point your phone at the banner and you'll see an augmented reality schedule of what's happening," said Janessa White, Hackfort Director.
Technology innovators have their own event on Friday. Hackfort is headlined by Nate Silver from the popular FiveThirtyEight blog.
And if you need a way to get around town and you have a wristband, you can ride any Valleyride bus for free.
