Where Summer Fun Begins

The Dorothy Olson Aquatic Center is Willmar's premier facility to beat the summer heat! Take the plunge on one of two raging water slides! One slide is fully enclosed the entire way down and the other open with both emptying into an attached plunge pool at the bottom. Go for a swim in the six-lane recreation pool with depths of 3 to 5 feet or enjoy some diving with the 1-meter diving boards standing over 10 foot crystal blue waters. For the younger guests, we have interactive play features and a mini slide all surrounded by a zero-depth entry pool with a max depth of 18-inches.
