Everything You Can Do in Sioux Falls This 4th of July Just like any weekend in Sioux Falls, you will have your pick of things to do this upcoming 4th of July weekend. It doesn't matter whether you're looking for fireworks, fitness, food, or just plain old fun, someone will be offering it up and all you have to do is join in! If you get to the end of the week and just want a little time for yourself or a lot of time with your friends, you can get an early start to your weekend at the Downtown First Friday & Eastbank Block Party.
