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, 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 try out the Poolside Climbing Wall. This new addition stands at 12 feet tall and lets swimmers climb as high as they can and make a splash into the crystal blue waters below at 10 feet deep. 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.
