Falls Park is over 128 acres north of downtown along the Big Sioux River. Each second 7,400 gallons drop 100 feet. The park has many platforms, including a five‑story observation tower. The park has a rich history with some of Sioux Falls' oldest buildings. Visitors say the park is absolutely beautiful at this time of year, with lights that are well put together. The Christmas lights and music do not disappoint; the lights dance to the music, and many drive through to listen. It is a must see every year and a place people love to return to again and again.
