A great family fun day in Sioux Falls is a trip to the Great Plains Zoo! The zoo is open year round but my favorite time to go is in the fall. The weather is nice and the animals are still all out on display. Admission for adults is around $8.00 and kids are under $5.00. So this is a very affordable day of family fun.
Pack a lunch and go have a family picnic after you go through at Lower Sherman Park which is adjoining the zoo parking lot. With a restroom area, picnic benches and playground equipment you have everything you need to keep the kids busy for the day! There is also a beautiful formal garden for the grown ups to check out. All of this is conveniently off of the 12th street exit on I-29 North and then south on Kiwanis Ave.
